This book was released on 2014 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Networked Control Systems are control systems, where the feedback loop is closed by a communication system. Within the past decades, the effects of the properties of the communication system, like loss, delay, or bandwidth constraints, on the control performance have been studied thoroughly. Since the properties of the communication system depend on the design of the communication system and its usage, the goal of this thesis is to work towards a joint design of the controller and the communication system for networked control systems. To achieve this goal, the thesis builds upon previous works from the field of networked control systems, where controller design methods for a communication system with given properties are developed, but takes into account that these properties depend on the design of the communication system and its usage. Based on well known ideas from communication theory, several methods to improve the control performance by optimizing the communication system are presented.

Available in PDF, EPUB and Kindle. Book excerpt: This book nds its origin in the WIDE PhD School on Networked Control Systems, which we organized in July 2009 in Siena, Italy. Having gathered experts on all the aspects of networked control systems, it was a small step to go from the summer school to the book, certainly given the enthusiasm of the lecturers at the school. We felt that a book collecting overviewson the important developmentsand open pr- lems in the eld of networked control systems could stimulate and support future research in this appealing area. Given the tremendouscurrentinterests in distributed control exploiting wired and wireless communication networks, the time seemed to be right for the book that lies now in front of you. The goal of the book is to set out the core techniques and tools that are ava- able for the modeling, analysis and design of networked control systems. Roughly speaking, the book consists of three parts. The rst part presents architectures for distributed control systems and models of wired and wireless communication n- works. In particular, in the rst chapter important technological and architectural aspects on distributed control systems are discussed. The second chapter provides insight in the behavior of communication channels in terms of delays, packet loss and information constraints leading to suitable modeling paradigms for commu- cation networks.
Book Synopsis Control and Optimization Based on Network Communication by : Xi-Ming Sun
Download or read book Control and Optimization Based on Network Communication written by Xi-Ming Sun and published by Springer Nature. This book was released on 2023-03-16 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book considers the problems of network-based control and optimization. As is known, network-based control has great advantages over traditional control systems because it may lead to easy installation and maintenance, low cost, and so on. Sometimes, network-based control is also necessary in many situations. For example, multi-agents may need to communicate with each other under wireless scenarios. On the other hand, the network may lead to some imperfect factors such as samplings, delays, transmission protocols, and packet losses. These factors may degrade the system performance and even lead to the instability of the control systems. This book aims at providing a modeling framework and analysis approach for the general nonlinear networked control systems based on the hybrid framework. The proposed results deal with very general nonlinear systems and help the readers understand the principle of nonlinear network-based control and optimization.
Book Synopsis Optimal and Robust Scheduling for Networked Control Systems by : Stefano Longo
Download or read book Optimal and Robust Scheduling for Networked Control Systems written by Stefano Longo and published by CRC Press. This book was released on 2018-09-03 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optimal and Robust Scheduling for Networked Control Systems tackles the problem of integrating system components—controllers, sensors, and actuators—in a networked control system. It is common practice in industry to solve such problems heuristically, because the few theoretical results available are not comprehensive and cannot be readily applied by practitioners. This book offers a solution to the deterministic scheduling problem that is based on rigorous control theoretical tools but also addresses practical implementation issues. Helping to bridge the gap between control theory and computer science, it suggests that the consideration of communication constraints at the design stage will significantly improve the performance of the control system. Technical Results, Design Techniques, and Practical Applications The book brings together well-known measures for robust performance as well as fast stochastic algorithms to assist designers in selecting the best network configuration and guaranteeing the speed of offline optimization. The authors propose a unifying framework for modelling NCSs with time-triggered communication and present technical results. They also introduce design techniques, including for the codesign of a controller and communication sequence and for the robust design of a communication sequence for a given controller. Case studies explore the use of the FlexRay TDMA and time-triggered control area network (CAN) protocols in an automotive control system. Practical Solutions to Your Time-Triggered Communication Problems This unique book develops ready-to-use engineering tools for large-scale control system integration with a focus on robustness and performance. It emphasizes techniques that are directly applicable to time-triggered communication problems in the automotive industry and in avionics, robotics, and automated manufacturing.
Book Synopsis Control Strategies and Co-Design of Networked Control Systems by : Héctor Benítez-Pérez
Download or read book Control Strategies and Co-Design of Networked Control Systems written by Héctor Benítez-Pérez and published by Springer. This book was released on 2018-07-31 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents Networked Control System (NCS) as a particular kind of a real-time distributed system (RTDS), composed of a set of nodes, interconnected by a network, and able to develop a complete control process. It describes important parts of the control process such as sensor and actuator activities, which rely on a real-time operating system, and a real-time communication network. As the use of common bus network architecture introduces different forms of uncertainties between sensors, actuators, and controllers, several approaches such as reconfigurable systems have been developed to tackle this problem. Moreover, modeling NCS is a challenging procedure, since there are several non-linear situations, like local saturations, uncertain time delays, dead-zones, or local situations, it is necessary to deal with. The book describes a novel strategy for modelling and control based on a fuzzy control approach and codesign strategies.

Book Synopsis Robust Control for Uncertain Networked Control Systems with Random Delays by : Dan Huang
Download or read book Robust Control for Uncertain Networked Control Systems with Random Delays written by Dan Huang and published by Springer Science & Business Media. This book was released on 2009-07-06 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Robust Control for Uncertain Networked Control Systems with Random Delays" addresses the problem of analysis and design of networked control systems when the communication delays are varying in a random fashion. The random nature of the time delays is typical for commercially used networks, such as a DeviceNet (which is a controller area network) and Ethernet network. The main technique used in this book is based on the Lyapunov-Razumikhin method, which results in delay-dependent controllers. The existence of such controllers and fault estimators are given in terms of the solvability of bilinear matrix inequalities. Iterative algorithms are proposed to change this non-convex problem into quasi-convex optimization problems, which can be solved effectively by available mathematical tools. Finally, to demonstrate the effectiveness and advantages of the proposed design method in the book, numerical examples are given in each designed control system.

This book was released on 2011-04-07 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Networked and Distributed Predictive Control presents rigorous, yet practical, methods for the design of networked and distributed predictive control systems – the first book to do so. The design of model predictive control systems using Lyapunov-based techniques accounting for the influence of asynchronous and delayed measurements is followed by a treatment of networked control architecture development. This shows how networked control can augment dedicated control systems in a natural way and takes advantage of additional, potentially asynchronous and delayed measurements to maintain closed loop stability and significantly to improve closed-loop performance. The text then shifts focus to the design of distributed predictive control systems that cooperate efficiently in computing optimal manipulated input trajectories that achieve desired stability, performance and robustness specifications but spend a fraction of the time required by centralized control systems. Key features of this book include: • new techniques for networked and distributed control system design; • insight into issues associated with networked and distributed predictive control and their solution; • detailed appraisal of industrial relevance using computer simulation of nonlinear chemical process networks and wind- and solar-energy-generation systems; and • integrated exposition of novel research topics and rich resource of references to significant recent work. A full understanding of Networked and Distributed Predictive Control requires a basic knowledge of differential equations, linear and nonlinear control theory and optimization methods and the book is intended for academic researchers and graduate students studying control and for process control engineers. The constant attention to practical matters associated with implementation of the theory discussed will help each of these groups understand the application of the book’s methods in greater depth.
Book Synopsis Networked Control Systems with Intermittent Feedback by : Domagoj Tolić
Download or read book Networked Control Systems with Intermittent Feedback written by Domagoj Tolić and published by CRC Press. This book was released on 2017-03-31 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Networked Control Systems (NCSs) are spatially distributed systems for which the communication between sensors, actuators and controllers is realized by a shared (wired or wireless) communication network. NCSs offer several advantages, such as reduced installation and maintenance costs, as well as greater flexibility, over conventional control systems in which parts of control loops exchange information via dedicated point-to-point connections. The principal goal of this book is to present a coherent and versatile framework applicable to various settings investigated by the authors over the last several years. This framework is applicable to nonlinear time-varying dynamic plants and controllers with delayed dynamics; a large class of static, dynamic, probabilistic and priority-oriented scheduling protocols; delayed, noisy, lossy and intermittent information exchange; decentralized control problems of heterogeneous agents with time-varying directed (not necessarily balanced) communication topologies; state- and output-feedback; off-line and on-line intermittent feedback; optimal intermittent feedback through Approximate Dynamic Programming (ADP) and Reinforcement Learning (RL); and control systems with exogenous disturbances and modeling uncertainties.

Novel methods for multi-agent systems ensure complete or clustered synchrony of agents with identical or with individual dynamics. The book includes numerous references to the most recent literature. Many methods are illustrated by numerical examples or experimental results.
Book Synopsis On the Performance Optimization of Reliable Networked Control Systems by : Hassan Hesham Halawa
Download or read book On the Performance Optimization of Reliable Networked Control Systems written by Hassan Hesham Halawa and published by . This book was released on 2015 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Networked Control Systems (NCSs) consist of sensors, controllers and actuators which are all interconnected via a network fabric. Such an architecture has proven advantageous for industrial communication networks compared to traditional approaches. Lately, Wireless NCSs (WNCSs) have also been rising in popularity due to their ease of installation and maintenance compared to equivalent wired NCSs. However, a significant drawback of WNCSs is the experienced wireless interference which arises from the shared nature of the wireless medium. In any NCS, the failure of a single component can cause complete control system failure in the absence of fault-tolerance. As a result of the ensuing system downtime due to such failures, large production losses could potentially occur. Thus, fault-tolerance is now becoming a crucial aspect of the design and evaluation of NCSs. Fault-tolerance can be implemented at various levels of an NCS in order to improve system reliability: either at the node level and/or at the network fabric level. Nevertheless, the incorporation of fault-tolerance in NCSs involves additional overhead traffic which can have a noticeable impact on the overall system performance. This overhead traffic may cause the real-time NCS to miss crucial control deadlines. Therefore, minimizing the amount of traffic overhead necessary for the implementation of fault-tolerance is desired. This research is focused on the design and performance optimization of reliable fault-tolerant NCSs and WNCSs. First, a fault-tolerant WNCS is proposed based on unmodified IEEE 802.11b implementing 1-out-of-3 controller level fault-tolerance utilizing a wired backbone. The interference tolerance of the system was quantified and certain performance optimizations were investigated in order to improve the overall system's interference resilience. Moreover, an additional fault-tolerant WNCS with a reliable wireless backbone is proposed. The proposed WNCS is based on unmodified IEEE 802.11g and implements 1-out-of-2 controller level fault-tolerance in addition to network fabric level fault-tolerance on the critical wireless backbone link using the Parallel Redundant Protocol (PRP). Second, a network fabric fault-tolerance methodology is investigated for wired Ethernet NCSs utilizing the Rapid Spanning Tree Protocol (RSTP). A performance optimization is proposed which halves the amount of traffic necessary for the implementation of fault-tolerance while guaranteeing system resilience to any individual network fabric failure. Furthermore, a reliability modeling methodology is developed for the proposed model. A case study is subsequently presented to compare reliability of different system architectures using typical industrial parameters. Finally, an expanded two cell model is developed which not only provides the same degree of network fabric level fault-tolerance but also controller level fault-tolerance.
Book Synopsis Networked Control Under Communication Constraints by : Kun Liu
Download or read book Networked Control Under Communication Constraints written by Kun Liu and published by Springer Nature. This book was released on 2020-04-27 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a time-delay approach to the analysis and synthesis of networked control systems (NCSs) under communication constraints. Differently from other approaches, the time-delay approach to NCSs allows communication delays to be larger than the sampling intervals in the presence of scheduling protocols. The book starts from a comprehensive introduction to three main approaches to sampled-data and networked control. It then focuses on time-delay approach, and the modelling of the closed-loop systems in the form of time-delay system. It presents discontinuous (in time) Lyapunov functional constructions that are efficient for NCSs in the presence of communications delays. Further, it highlights time-delay approaches developed to model and analyze NCSs under communication constraints, with a particular focus on dynamic quantization, round-robin, try-once-discard and stochastic protocols. The results are first presented for the continuous-time NCSs and then extended to discrete-time NCSs. Discussing recent developments in Lyapunov-based analysis of NCSs under communication constraints, the book is a valuable resource for researchers interested in sampled-data and networked control, and time-delay systems, as well as for graduate students in automatic control and systems theory.

This book was released on 2015-12-31 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of jointly designing a robust controller and an intelligent scheduler for networked control systems (NCSs) is addressed in this thesis. NCSs composing of multiple plants that share a single channel communication network with uncertain time-varying transmission times are modeled as switched polytopic systems with additive norm-bounded uncertainty. Switching is deployed to represent scheduling, the polytopic uncertainty to overapproximatively describe the uncertain time-varying transmission times. Based on the resulting NCS model and a state feedback control law, the control and scheduling codesign problem is then introduced and formulated as a robust (minimax) optimization problem with the objective of minimizing the worst-case value of an associated infinite time-horizon quadratic cost function. Five robust codesign strategies are investigated for tackling the introduced optimization problem, namely: Periodic control and scheduling (PCS), Receding-horizon control and scheduling (RHCS), Implementation-aware control and scheduling (IACS), Event-based control and scheduling (EBCS), Prediction-based control and scheduling (PBCS). All these codesign strategies are determined from LMI optimization problems based on the Lyapunov theory. The properties of each are evaluated and compared in terms of computational complexity and control performance based on simulation and experimental study, showing their effectiveness in improving the performance while utilizing the limited communication resources very efficiently.
