This book was released on 2014-01-03 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last two decades have witnessed considerable progress in the study of underactuated robotic systems (URSs). Control Design and Analysis for Underactuated Robotic Systems presents a unified treatment of control design and analysis for a class of URSs, which include systems with multiple-degree-of-freedom and/or with underactuation degree two. It presents novel notions, features, design techniques and strictly global motion analysis results for these systems. These new materials are shown to be vital in studying the control design and stability analysis of URSs. Control Design and Analysis for Underactuated Robotic Systems includes the modelling, control design and analysis presented in a systematic way particularly for the following examples: l directly and remotely driven Acrobots l Pendubot l rotational pendulum l counter-weighted Acrobot 2-link underactuated robot with flexible elbow joint l variable-length pendulum l 3-link gymnastic robot with passive first joint l n-link planar robot with passive first joint l n-link planar robot with passive single joint double, or two parallel pendulums on a cart l 3-link planar robots with underactuation degree two 2-link free flying robot The theoretical developments are validated by experimental results for the remotely driven Acrobot and the rotational pendulum. Control Design and Analysis for Underactuated Robotic Systems is intended for advanced undergraduate and graduate students and researchers in the area of control systems, mechanical and robotics systems, nonlinear systems and oscillation. This text will not only enable the reader to gain a better understanding of the power and fundamental limitations of linear and nonlinear control theory for the control design and analysis for these URSs, but also inspire the reader to address the challenges of more complex URSs.

This book was released on 2009 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper proposes a new robotic planar two-link manipulator design for educational use. Planar two-link manipulators are among the most accessible two-degree-of-freedom robots for students because they function like human arms. As a result they are ideal for laboratory teaching environments. While previous designs using belt-driven arms served adequately, this new design possesses a number of features that were not possible with the previous design, including more intuitive simplified dynamics, an expanded workspace allowing multiple full rotations, and the ability to be easily reconfigured into an acrobot (an underactuated double-pendulum which can be stabilized in a vertical configuration while being actuated only at the middle joint). The governing equations of the system are derived and an analysis of velocity control in the xy plane is perform and a control methodology is also presented by which the arm can be stabilized vertically while in its acrobot configuration. A Discussion of tradeoffs relevant to the future design of similar systems is also presented.

This book was released on 2013-11-18 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph provides readers with tools for the analysis, and control of systems with fewer control inputs than degrees of freedom to be controlled, i.e., underactuated systems. The text deals with the consequences of a lack of a general theory that would allow methodical treatment of such systems and the ad hoc approach to control design that often results, imposing a level of organization whenever the latter is lacking. The authors take as their starting point the construction of a graphical characterization or control flow diagram reflecting the transmission of generalized forces through the degrees of freedom. Underactuated systems are classified according to the three main structures by which this is found to happen—chain, tree, and isolated vertex—and control design procedures proposed. The procedure is applied to several well-known examples of underactuated systems: acrobot; pendubot; Tora system; ball and beam; inertia wheel; and robotic arm with elastic joint. The text is illustrated with MATLABsup®/sup/Simulink® simulations that demonstrate the effectiveness of the methods detailed./ppReaders interested in aircraft, vehicle control or various forms of walking robot will be able to learn from iUnderactuated Mechanical Systems

This book was released on 2024-10-13 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various modelling and control of two-link flexible manipulators are presented in this book. The lumped parameter modelling method and the assumed modes method modelling are comprehensively reviewed. The book also reviews the trajectory tracking problem and tip trajectory tracking problem along with the suppression of tip deflection of the links. An exponential time varying signal and a chaotic signal are considered as the desired trajectories. The identical/ non-identical slave manipulator is synchronised with the controlled master manipulator so that the slave manipulator indirectly follows the desired manipulator.
Download or read book Feedback Control of a Three link Planar Under actuated Manipulator Using a surge Velocity written by Pernell A. Jordan and published by . This book was released on 1993 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: An under-actuated robot manipulator is one that has fewer number of joint actuators than the number of degrees of freedom of the manipulator. Such manipulators are studied with the objective of developing smarter mechanical systems; ones that can provide low-cost automation, and enable design simplification. While in space these manipulators can afford to have any kind of mechanical structure, on earth they need to be strictly planar to be feasible. In this paper, we develop a control scheme for a three link planar robot manipulator with two actuators such that it can reach any joint configuration from any other. We assume that the first joint of the robot is passive, and is provided with a brake and a rotary dashpot. We show that our control is robust to the variations in certain parameters and unmodelled dynamics like stiction.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Recently the use of robot manipulators has been increasing in many applications such as medical applications, automobile, construction, manufacturing, military, space, etc. However, current rigid manipulators have high inertia and use actuators with large energy consumption. Moreover, rigid manipulators are slow and have low payload-to arm-mass ratios because link deformation is not allowed. The main advantages of flexible manipulators over rigid manipulators are light in weight, higher speed of operation, larger workspace, smaller actuator, lower energy consumption and lower cost. However, there is no adequate closed-form solutions exist for flexible manipulators. This is mainly because flexible dynamics are modeled with partial differential equations, which give rise to infinite dimensional dynamical systems that are, in general, not possible to represent exactly or efficiently on a computer which makes modeling a challenging task. In addition, if flexibility nature wasn’t considered, there will be calculation errors in the calculated torque requirement for the motors and in the calculated position of the end-effecter. As for the control task, it is considered as a complex task since flexible manipulators are non-minimum phase system, under-actuated system and Multi-Input/Multi-Output (MIMO) nonlinear system. This thesis focuses on the development of dynamic formulation model and three control techniques aiming to achieve accurate position control and improving dynamic stability for Two-Link Flexible Manipulators (TLFMs). LQR controller is designed based on the linearized model of the TLFM; however, it is applied on both linearized and nonlinear models. In addition to LQR, Backstepping and Sliding mode controllers are designed as nonlinear control approaches and applied on both the nonlinear model of the TLFM and the physical system. The three developed control techniques are tested through simulation based on the developed dynamic formulation model using MATLAB/SIMULINK. Stability and performance analysis were conducted and tuned to obtain the best results. Then, the performance and stability results obtained through simulation are compared. Finally, the developed control techniques were implemented and analyzed on the 2-DOF Serial Flexible Link Robot experimental system from Quanser and the results are illustrated and compared with that obtained through simulation.
