Available in PDF, EPUB and Kindle. Book excerpt: Flexible robotic manipulators pose various challenges in research as compared to rigid robotic manipulators, ranging from system design, structural optimization, and construction to modeling, sensing, and control. Although significant progress has been made in many aspects over the last one-and-a-half decades, many issues are not resolved yet, and simple, effective, and reliable controls of flexible manipulators still remain an open quest. Clearly, further efforts and results in this area will contribute significantly to robotics (particularly automation) as well as its application and education in general control engineering. To accelerate this process, the leading experts in this important area present in this book the state of the art in advanced studies of the design, modeling, control and applications of flexible manipulators.

Available in PDF, EPUB and Kindle. Book excerpt: The problem of robot manipulator controller design in the presence of joint flexibility is addressed. The specific goal is to design a controller that yields good tracking performance in spite of parametric uncertainty. Feedback linearization, robust observers, singular perturbation technique, and adaptive control are different approaches that are theoretically analyzed. Experimental results on a single-link, flexible joint arm are also presented. Although each controller has its advantages and drawbacks, all of the design methods yield improved performance when compared to controller designs based upon rigid joint models.

Available in PDF, EPUB and Kindle. Book excerpt: This monograph is concerned with the development and implementation of nonlinear mathematical techniques for feedback control and shape design of robot manipulators whose links have considerable structural flexibility. Several nonlinear control and observation techniques are studied and implemented by simulations and experiments in a laboratory setup. These techniques include integral manifolds in singular perturbation theory, nonlinear input-output decoupling, nonlinear observers and sliding control. The study of dynamic properties and control techniques for flexible-link manipulators can also be a framework for designing the mechanical shape and material of these systems such that improved properties can be achieved in order to facilitate the control problem. Therefore, structural shape optimization is considered as a means of improving the dynamic behaviour of flexible-link manipulators.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the application of novel linear time invariant techniques to the design of low-order controllers for flexible joint manipulators. The nonlinear manipulator model is linearized via the perturbation method about an unstable operating point. Some nonlinear terms are treated as an external disturbance, and parametric uncertainty is represented as the structured uncertainty of the nominal plant. The $Hsb{infty}$-norm approach is then utilized to design a robust state feedback controller to stabilize the linear system and to give a specified bound on the disturbance rejection of the closed-loop system with enough robustness margin as to stabilize the actual nonlinear model. The nominal linear system with the state feedback controller determines the reference dynamics to be retained by the low-order controller based on the projective controls approach. The residual dynamics of the closed-loop system are selected under a suitable criterion to enhance disturbance rejection. The nonlinear model of the manipulator is also treated as a nonlinear system with structured uncertainty and sufficient conditions are determined for stability and disturbance rejection using linear state feedback and full-order controllers. Examples are given in the case of the one-link and two-link manipulators. The decentralized control option is also studied. The design of the controllers is based on a linear decoupled model obtained from the linearized model. The methodology here follows the same two phases of design used in the centralized case. Adaptive mechanisms are illustrated to improve the robust performance of the low-order decentralized control.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation is concerned with investigating robust approaches for the control of pneumatic muscle systems. Pneumatic muscle is a novel type of actuator. Besides having a high ratio of power to weight and flexible control of movement, it also exhibits many analogical behaviors to natural skeletal muscle, which makes them the ideal candidate for applications of anthropomorphic robotic systems. In this dissertation, a new phenomenological model of pneumatic muscle developed in the Human Sensory Feedback Laboratory at Wright Patterson Air Force Base is investigated. The closed loop stability of a one-link planar arm actuated by two pneumatic muscles using linear state feedback is proved. Robotic systems actuated by pneumatic muscles are time-varying and nonlinear due to load variations and uncertainties of system parameters caused by the effects of heat. Sliding mode control has the advantage that it can provide robust control performance in the presence of model uncertainties. Therefore, it is mainly utilized and further complemented with other control methods in this dissertation to design the appropriate controller to perform the tasks commanded by system operation. First, a sliding mode controller is successfully proposed to track the elbow angle with bounded error in a one-Joint limb system with pneumatic muscles in bicep/tricep configuration. Secondly, fuzzy control, which aims to dynamically adjust the sliding surface, is used along with sliding mode control. The so-called fuzzy sliding mode control method is applied to control the motion of the end-effector in a two-Joint planar arm actuated by four groups of pneumatic muscles. Through computer simulation, the fuzzy sliding mode control shows very good tracking accuracy superior to nonfuzzy sliding mode control. Finally, a two joint planar arm actuated by four groups of pneumatic muscles operated in an assumed industrial environment is presented. Based on the model, an integral sliding mode control scheme is proposed as an ultimate solution to the control of systems actuated by pneumatic muscles. As the theoretical proof and computer simulations show, the integral sliding mode controller, with strong robustness to model uncertainties and external perturbations, is superior for performing the commanded control assignment. Based on the investigation in this dissertation, integral sliding mode control proposed here is a very promising robust control approach to handle systems actuated by pneumatic muscles.

The lumped parameter modelling method and the assumed modes method modelling are reviewed comprehensively. 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.

Available in PDF, EPUB and Kindle. Book excerpt: AfterasurveypaperbyUtkininthelate1970s,slidingmodecontrolmeth- ologies emerged as an e?ective tool to tackle uncertainty and disturbances which are inevitable in most of the practical systems. Sliding mode control is a particular class of variable structure control which was introduced by Emel’yanov and his colleagues. The design paradigms of sliding mode c- trol has now become a mature design technique for the design of robust c- troller of uncertain system. In sliding mode technique, the state trajectory of the system is constrained on a chosen manifold (or within some neighb- hood thereof) by an appropriatecontrolaction. This manifold is also called a switching surface or a sliding surface. During sliding mode, system dynamics is governed by the chosen manifold which results in a well celebrated inva- ance property towards certain classes of disturbance and model mismatches. The purpose of this monograph is to give a di?erent dimension to sl- ing surface design to achieve high performance of the system. Design of the switching surface is vital because the closed loop dynamics is governed by the parameters of the sliding surface. Therefore sliding surface should be - signed to meet the closed loop speci?cations. Many systems demand high performance with robustness. To address this issue of achieving high perf- mance with robustness, we propose nonlinear surfaces for di?erent classes of systems. The nonlinear surface is designed such that it changes the system’s closed-loop damping ratio from its initial low value to a ?nal high value.
