Book excerpt: Cable actuated parallel manipulators, also called cable robots, share many features in common with traditional parallel manipulators. However, such systems additionally feature considerably large workspace, large payload handling capacity and good disturbance rejection potentials over traditional parallel manipulator by virtue of the cable-band actuation. However, realizing their benefits poses numerous challenges to researchers. One critical issue is the unidirectional nature of forces exerted by cables, which only allows them to endure tensile force when performing tasks. Another critical issue in such systems is the actuation redundancy. In this thesis, we will examine these two aspects in the context of motion and active stiffness control scenarios. First, we study the implication of actuation redundancy in the context of controller design and workspace (task space) stiffness property of cable robot system. Then suitable trajectory tracking control schemes are developed to achieve two different secondary goals under positive control input constraint: (a) minimal energy consumption among actuations; (b) active stiffness control to improve disturbance-rejection. Finally, these control schemes are evaluated within a virtual prototyping (VP) implementation framework.

Book Synopsis Synchronized Trajectory Tracking Control for Parallel Robotic Manipulators by : Lu Ren
Download or read book Synchronized Trajectory Tracking Control for Parallel Robotic Manipulators written by Lu Ren and published by . This book was released on 2006 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, in order to solve the trajectory tracking control problem of parallel robotic manipulators, we propose a new control approach, termed synchronized control. In this control scheme, considering the closed-loop kinematic chain mechanism of parallel robotic manipulators, an additional feedback signal, termed the synchronization error, is employed. Different from the traditional tracking errors, i.e., position errors and velocity errors, the synchronization error represents the coordination degree of the active joints in a parallel robotic manipulator. Therefore, compared with traditional control approaches, e.g., PD control and PID control, the employment of the synchronization error in a synchronized controller improves the tracking performance of a parallel robotic manipulator. Experimental results also demonstrate this claim. With respect to different operation conditions and tracking performance requirements, based on the synchronized control, we propose two new control approaches, termed adaptive synchronized (A-S) control and convex synchronized (C-S) control. The former is proposed to address unknown parameters in the dynamic model of a parallel robotic manipulator during practical operations. Through estimating unknown parameters during tracking control process by an estimator, the influence of the unknown parameters is eliminated. The latter is proposed to address the multiple simultaneous specification (MSS) problem during trajectory tracking. By using the convex combination method, the C-S controller is designed through combining multiple synchronized controllers. This control approach substantially lessens the burden of tuning control gains. In principle, the proposed synchronized control, A-S control and C-S control are all suitable for parallel robotic manipulators with various structures. Experiments conducted on a 3-DOF P-R-R planar parallel robotic manipulator demonstrate the validity and effectiveness of these three control approaches.
Book Synopsis Parallel Manipulators by : Jee-Hwan Ryu
Download or read book Parallel Manipulators written by Jee-Hwan Ryu and published by BoD – Books on Demand. This book was released on 2008-04-01 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parallel manipulators are characterized as having closed-loop kinematic chains. Compared to serial manipulators, which have open-ended structure, parallel manipulators have many advantages in terms of accuracy, rigidity and ability to manipulate heavy loads. Therefore, they have been getting many attentions in astronomy to flight simulators and especially in machine-tool industries.The aim of this book is to provide an overview of the state-of-art, to present new ideas, original results and practical experiences in parallel manipulators. This book mainly introduces advanced kinematic and dynamic analysis methods and cutting edge control technologies for parallel manipulators. Even though this book only contains several samples of research activities on parallel manipulators, I believe this book can give an idea to the reader about what has been done in the field recently, and what kind of open problems are in this area.

Book Synopsis Trajectory Tracking Control of Parallel Manipulator with Integral Manifold and Observer by : Zhengsheng Chen
Download or read book Trajectory Tracking Control of Parallel Manipulator with Integral Manifold and Observer written by Zhengsheng Chen and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In view of the problem that notable flexible displacement will occur for parallel manipulators when operating at high speed, the composite controller based on the integral manifold and high-gain observer is proposed for trajectory tracking and the 3RRR parallel manipulator is taken as the object. Based on the stiffness matrix, the small variable is introduced to decompose the rigid-flexible coupling dynamic model into slow and fast subsystem. For the slow subsystem, the backstepping control is applied for rigid motion tracking. In order to account for the links,Äô flexible displacement the corrective torque is deduced, and the compensation for the flexible displacement is realized. For the fast subsystem, the sliding mode control is utilized to suppress the vibration. The high-gain observer is designed to avoid the measurement of the curvature rate of flexible links. Also, the stability of the overall system is proven with the Lyapunov stability theorem and the upper bound of the small variable is obtained. At last, the proposed composite controller together with the singular perturbation control and the rigid body model-based backstepping control are simulated, and vibration suppression and tracking performances are compared to validate the proposed control scheme.

Book Synopsis Symbolic Kinematics and Dynamics Analysis and Control of a General Stewart Parallel Manipulator by : Yao Wang
Download or read book Symbolic Kinematics and Dynamics Analysis and Control of a General Stewart Parallel Manipulator written by Yao Wang and published by . This book was released on 2008 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Application of parallel manipulator has received a lot of attention recently in the industry and the robotic community due to its high accuracy, high rigidity, high operation speed, high load capacity and high stiffness as compared with the conventional serial manipulator. One of the most popular parallel manipulators that are commonly used for aircraft simulator is the general purpose 6 degree-of-freedom (DOF) Stewart parallel manipulator. Despite these advantages, the kinematic and dynamic analyses are extremely complicated. Such models are important in terms of qualitative analysis of the required actuator forces to realize certain end-effector task (inverse dynamics), and computing the corresponding end-effector task based on certain input to the system (forward dynamics). However, till date, not much general symbolic solution is reported to aid the above process. Most of the prior work required some form of heuristic, or introduction of extra spring/damper elements to approximate the solutions. This thesis addresses the possibility in using the state-of-the-art symbolic manipulation software tool to derive the general kinematic and dynamic equation of motion of the system so that more accurate solution can be computed. However, there are still consideration are needed to accurately simulate such systems. We address these issues using the example of Stewart parallel manipulator and highlight the solution to the corresponding challenges. Control using stabilizing inverse dynamics was implemented to enhance trajectory tracking of the system.
Book Synopsis Trajectory Planning for Automatic Machines and Robots by : Luigi Biagiotti
Download or read book Trajectory Planning for Automatic Machines and Robots written by Luigi Biagiotti and published by Springer Science & Business Media. This book was released on 2008-10-23 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the problems related to planning motion laws and t- jectories for the actuation system of automatic machines, in particular for those based on electric drives, and robots. The problem of planning suitable trajectories is relevant not only for the proper use of these machines, in order to avoid undesired e?ects such as vibrations or even damages on the mech- ical structure, but also in some phases of their design and in the choice and sizing of the actuators. This is particularly true now that the concept of “el- tronic cams” has replaced, in the design of automatic machines, the classical approach based on “mechanical cams”. The choice of a particular trajectory has direct and relevant implications on several aspects of the design and use of an automatic machine, like the dimensioning of the actuators and of the reduction gears, the vibrations and e?orts generated on the machine and on the load, the tracking errors during the motion execution. For these reasons, in order to understand and appreciate the peculiarities of the di?erent techniques available for trajectory planning, besides the ma- ematical aspects of their implementation also a detailed analysis in the time and frequency domains, a comparison of their main properties under di?erent points of view, and general considerations related to their practical use are reported.
