Available in PDF, EPUB and Kindle. Book excerpt: Control of high-speed, light-weight robotic manipulators is a challenge because of their special dynamic characteristics. In this work, a two-stage control algorithm for the position control of flexible manipulators is proposed. First, the more complex, flexible robot system is replaced by a simplified hypothetical rigid body system (HRRA) with off-line trajectory planning. This reduces the complexity of the controller design for the flexible robotic arm. A parameter-optimization approach was adopted to minimize the difference between these two models in this stage. Also, a comparison of computational efficiency is made among the methods of calculus-of-variations, dynamic-programming, and the proposed parameter-optimization. At the second stage, simple linear state feedback controllers, based on the simplified hypothetical rigid body model, are proposed to control the actual robotic system. With the feedback gains selected properly by the pole-placement and linear quadratic methods, the results show satisfactory achievement of the motion objectives. The algorithm is implemented for a two-link rigid/flexible robotic arm, and the results indicate that the procedure is capable of providing effective control with much simpler computational requirements than those of procedures published previously.

Download or read book Distributed Parameter Modeling and Boundary Control of Flexible Manipulators written by Jinkun Liu and published by Springer. This book was released on 2018-04-16 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book investigates fundamental issues in flexible manipulator systems, including distributed parameter modeling and boundary controller design. It presents theoretical explorations of several fundamental problems concerning the dynamics and control of these systems. By integrating fresh concepts and results to form a systematic approach to control, it also provides a basic theoretical framework. In turn, the book offers a comprehensive treatment of flexible manipulator systems, addressing topics ranging from related distributed parameter modeling and advanced boundary controller design for these systems with input constraint, to active control with output constraint. In brief, the book addresses dynamical analysis and control design for flexible manipulator systems. Though primarily intended for researchers and engineers in the control system and mechanical engineering community, it can also serve as supplemental reading on the modeling and control of flexible manipulator systems at the postgraduate level.
Download or read book Dynamics and Control of Light Weight Flexible Manipulators written by Amor Jnifene and published by . This book was released on 1996 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current robot manipulators are controlled using methods that do not take into account the links and joints flexibility. Consequently, tasks are usually carried in a slow fashion. The objective of this research is to improve the performance of light weight flexible manipulators by developing dynamic models and control strategies that include the effects of the links flexibility. Toward achieving this objective, the dynamic model of a single link flexible manipulator has been developed. Two hermit cubic functions are used in conjunction with the deflection and the slope at the tip of the link in order to express the deflection at any point along the link. The model is used to simulate the response of the single link manipulator and its ability to follow various trajectories under collocated control. Even though collocated control such as the computed torque method leads to asymptotic stability in the case of rigid link manipulators, the end point of the single link flexible manipulator has shown sustained oscillations under this type of control. In order to improve the performance of the single link and reduce the tip deflection, dynamic stiffening has been added to the link by using the angular position of a point along the link as the controlled variable. This control method is referred to as the non collocated control. Simulations of the robot motion under non collocated control has shown a significant reduction in the position error of the end point. In order to increase the damping of the flexible link, a new approach referred to as the Computed Torque/Delayed Deflection (CTDD) has been used. The CTDD approach combines the non collocated control with a delayed deflection at the point being used for non collocation feedback. The fastest decay in the end point vibrations was obtained when the delay time is selected to be half the period of the lowest frequency in the system. The CTDD has been extended to the case of a two link flexible manipulator. Simulations results for the tracking performance of the two link flexible manipulator have been carried out using two paths: A straight line path and a four points path. The advantages of using the CTDD approach are outlined by comparing its performance to those of a collocated control (computed torque method) and the non collocated control.

This book was released on 2021-11-28 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the dynamic analysis of rigid-flexible robots and multibody systems with serial as well as closed-loop architecture. The book presents a formulation of dynamic model of rigid-flexible robots based on the unique approach of de-coupling of natural orthogonal complements of velocity constraints. Based on this formulation, a computationally efficient and numerically stable forward dynamics algorithms for serial-chain and closed-loop robotic systems with rigid or flexible or rigid-flexible links is presented. The proposed algorithm is shown to be a numerically efficient for forward dynamics based on the investigation methodologies built on eigen value analytics. Precision and functionality of the simulation algorithms is presented/illustrated with application on different serial and closed-loop systems (both planar and spatial types). Some of the major robotic arms used to illustrate the proposed dynamic formulation and simulation algorithms are PUMA robot, Stanford robot arm, and Canadarm. It is envisaged that the book will be useful for researchers working on the development of rigid-flexible robots for use in defense, space, atomic energy, ocean exploration, and the manufacturing of biomedical equipment.

Download or read book Flexible Joint Robots written by Mark C. Readman and published by CRC Press. This book was released on 1994-07-13 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Joint flexibility from harmonic or direct drives or flexible couplings limits the performance of robots. Performance can be improved by taking into account the fast dynamics that are introduced by joint flexibility. High gain acceleration feedback from the link angles simplifies the robot dynamics, but is limited by joint flexibility. One solution is to use joint torque feedback to stabilize the fast dynamics. In light of this, drive systems that incorporate joint torque sensors are being developed. Flexible Joint Robots is the first book to consider the myriad problems and potential solutions that affect flexible joint robot design. The book covers fundamental concepts, including joint torque feedback control laws, acceleration feedback, and adaptive control laws. It presents a dynamic model of a flexible joint robot in several coordinate systems and includes an analysis of the fast dynamics.
