Download or read book Automatic Flight Control Systems written by Thomas Lombaerts and published by BoD – Books on Demand. This book was released on 2012-01-18 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of flight control is inseparably linked to the history of aviation itself. Since the early days, the concept of automatic flight control systems has evolved from mechanical control systems to highly advanced automatic fly-by-wire flight control systems which can be found nowadays in military jets and civil airliners. Even today, many research efforts are made for the further development of these flight control systems in various aspects. Recent new developments in this field focus on a wealth of different aspects. This book focuses on a selection of key research areas, such as inertial navigation, control of unmanned aircraft and helicopters, trajectory control of an unmanned space re-entry vehicle, aeroservoelastic control, adaptive flight control, and fault tolerant flight control. This book consists of two major sections. The first section focuses on a literature review and some recent theoretical developments in flight control systems. The second section discusses some concepts of adaptive and fault-tolerant flight control systems. Each technique discussed in this book is illustrated by a relevant example.

Book Synopsis Linear and Nonlinear Control of Small-Scale Unmanned Helicopters by : Ioannis A. Raptis
Download or read book Linear and Nonlinear Control of Small-Scale Unmanned Helicopters written by Ioannis A. Raptis and published by Springer Science & Business Media. This book was released on 2010-09-28 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been significant interest for designing flight controllers for small-scale unmanned helicopters. Such helicopters preserve all the physical attributes of their full-scale counterparts, being at the same time more agile and dexterous. This book presents a comprehensive and well justified analysis for designing flight controllers for small-scale unmanned helicopters guarantying flight stability and tracking accuracy. The design of the flight controller is a critical and integral part for developing an autonomous helicopter platform. Helicopters are underactuated, highly nonlinear systems with significant dynamic coupling that needs to be considered and accounted for during controller design and implementation. Most reliable mathematical tools for analysis of control systems relate to modern control theory. Modern control techniques are model-based since the controller architecture depends on the dynamic representation of the system to be controlled. Therefore, the flight controller design problem is tightly connected with the helicopter modeling. This book provides a step-by-step methodology for designing, evaluating and implementing efficient flight controllers for small-scale helicopters. Design issues that are analytically covered include: • An illustrative presentation of both linear and nonlinear models of ordinary differential equations representing the helicopter dynamics. A detailed presentation of the helicopter equations of motion is given for the derivation of both model types. In addition, an insightful presentation of the main rotor's mechanism, aerodynamics and dynamics is also provided. Both model types are of low complexity, physically meaningful and capable of encapsulating the dynamic behavior of a large class of small-scale helicopters. • An illustrative and rigorous derivation of mathematical control algorithms based on both the linear and nonlinear representation of the helicopter dynamics. Flight controller designs guarantee that the tracking objectives of the helicopter's inertial position (or velocity) and heading are achieved. Each controller is carefully constructed by considering the small-scale helicopter's physical flight capabilities. Concepts of advanced stability analysis are used to improve the efficiency and reduce the complexity of the flight control system. Controller designs are derived in both continuous time and discrete time covering discretization issues, which emerge from the implementation of the control algorithm using microprocessors. • Presentation of the most powerful, practical and efficient methods for extracting the helicopter model parameters based on input/output responses, collected by the measurement instruments. This topic is of particular importance for real-life implementation of the control algorithms. This book is suitable for students and researches interested in the development and the mathematical derivation of flight controllers for small-scale helicopters. Background knowledge in modern control is required.

Download or read book Heavy Lift Helicopter Flight Control System. Volume II. - Primary Flight Control System Development and Feasibility Demonstration written by and published by . This book was released on 1977 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Army's Heavy Lift Helicopter Advanced Technology Component Program required the design, development and inflight feasibility demonstration of an electrohydraulic flight control system, referred to as fly-by-wire. Total flight testing encompassed evaluation and demonstration in two parts. First, a direct electrical linkage was successfully demonstrated in September 1973. Subsequently, an automatic flight control system was installed and evaluated with the direct electrical linkage. This volume describes the primary flight control system; its design features, installation test. Included also is a report of a related activity to design and evaluate, in laboratory tests, a compatible cockpit controller subsystem in which pilot commands are converted to electrical signals. Standard pilot interface features, such as magnetic brakes, stick position trim and force trim are included. To interface with the automatic flight control system, controller driver actuators are included.

Book Synopsis Flight Control Design for an Autonomous Rotorcraft Using Pseudo-sliding Mode Control and Waypoint Navigation by : Nicolas Joseph Mallory
Download or read book Flight Control Design for an Autonomous Rotorcraft Using Pseudo-sliding Mode Control and Waypoint Navigation written by Nicolas Joseph Mallory and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of robust automated flight control systems for aircraft of varying size and complexity is a topic of continuing interest for both military and civilian industries. By merging the benefits of robustness from sliding mode control (SMC) with the familiarity and transparency of design tradeoff offered by frequency domain approaches, this thesis presents pseudo-sliding mode control as a viable option for designing automated flight control systems for complex six degree-of-freedom aircraft. The infinite frequency control switching of SMC is replaced, by necessity, with control inputs that are continuous in nature. An introduction to SMC theory is presented, followed by a detailed design of a pseudo-sliding mode control and automated flight control system for a six degree-of-freedom model of a Hughes OH6 helicopter. This model is then controlled through three different waypoint missions that demonstrate the stability of the system and the aircraft's ability to follow certain maneuvers despite time delays, large changes in model parameters and vehicle dynamics, actuator dynamics, sensor noise, and atmospheric disturbances.
