This book was released on 2012-12-06 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the though that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemi nation. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 37 (thesis year 1992) a total of 12,549 thesis titles from 25 Canadian and 153 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 37 reports theses submitted in 1992, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

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 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.
Book Synopsis Nonlinear Control for Two-Link Flexible Manipulator by : Mohamed Ibrahim Shalaby

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.
