Available in PDF, EPUB and Kindle. Book excerpt: Complex and expensive electro-hydraulic systems have shouldered the workload for remote cleanup operations in radiological and toxicological areas in the past; the payload, reach and speed requirements of most applications have demanded their use. Electromechanically actuated systems (EAS) however offer an alternative that in comparison is much more reliable and maintainable. The problems faced in implementing the EAS are in high payload operations where the hydraulic systems hold a clear power density advantage. For the EAS to compete in the area of torque, very large DC motors have been implemented which make them obsolete in restricted work space areas and prove to be lacking in high-speed applications. New research suggests that this may be overcome by the use of a variable speed transmission or discrete variable transmission (DVT) system to spread the EAS torque-speed characteristics over a wider output speed range. This concept is called Transmission Based Actuators (TBA). This concept will facilitate the use of much smaller high speed motors which, when coupled with a DVT, can offer low speeds at high torques and high speed at low torques thereby matching the performance and size of the hydraulic systems [1]. The work here provides the detailed design of such a DVT comprised of three planetary gear stages. The full design process is discussed along with kinematic, dynamic and parameter identification analyses. The design process consists of determining the configuration, mechanical design for each element and selection of components such as bearings. snap rings and materials. The parameter identification portion attempts to quantify constants, such as damping and inertia, which affect the operation of the system. The Matlab System Identification Toolbox (SID) was utilized to accomplish this. This required the creation of a two-degree of freedom dynamic model and the capturing of operational data to estimate the parameters.

Download or read book Adaptive Systems in Control and Signal Processing 1983 written by I. D. Landau and published by Elsevier. This book was released on 2014-06-28 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adaptive Systems in Control and Signal Processing 1983 is a compendium of papers presented at the International Federation of Automatic Control in San Francisco on June 20-22, 1983. One paper addresses the results through comparative alternative algorithms in adaptive control of linear time invariant and time varying systems. Another paper presents a method in computer simulation of a wide range of stable plants to achieve an alternative approach in designing an adaptive control system. The book also compares the stability and the sensitivity approach involving the design of model-reference adaptive systems. The authors involved explain that the sensitivity concept determines the "dynamic speed of adaptation," while the stability concept focuses on finding a linear compensator for any deviant signal. One paper proposes an indirect adaptive control algorithm for MIMO square full rank minimum phase systems, while another paper discusses the application of the discrete time multivariable adaptive control system, to non-minimum phase plants with an unknown dead time. This book can prove valuable to engineers and researchers of electrical, computer, and mechanical engineering. It can also be helpful for technicians and students dealing with automatic control and telecontrol.

Download or read book Design Modeling Analysis Control and Testing of an Infinitely Variable Transmission written by Xuefeng Wang and published by . This book was released on 2017 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: A novel infinitely variable transmission (IVT) based on scotch yoke systems is designed to provide a continuously varied output-to-input speed ratio from zero to a specified value, which can be widely used in wind turbine and vehicle applications. Its zero-speed-ratio-start-up feature and scalability are especially suitable for construction or agriculture vehicles. The IVT consists of a pair of noncircular gears and the main body including two modules: an input-control module and a motion conversion module; the speed ratio is changed in the motion conversion module with use of scotch yoke systems. The Lagrangian approach is used to develop its dynamic model that can be used to design a robust and efficient controller, and the steady-state solution of the IVT is obtained using the incremental harmonic balance (IHB) method. A modified IHB method is developed here to significantly increase the computational efficiency and reduce the derivation complexity comparing with the classic IHB method, where the residual is approximated by the fast Fourier transform, and Jacobian matrix is approximated by Broyden’s method. A time-delay feedback controller combined with an open loop control is used for the IVT to stabilize the system and adjust its average input speed to a desired value for a vehicle application. Local stability of the system at the equilibrium can be proved by the stability of its linearized dynamic equation that is a time-delay linear time periodic (LTP) system, and its stability is numerically evaluated by converting the time-delay LTP system to a partial differential equation without time delay. A prototype of the IVT is manufactured and assembled. Functionality of the IVT is validated and parameter estimation is conducted for use in the design of the controller, and driving tests using feedback control are conducted to examine the performance of the controller.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is the published Proceedings of selected papers from the IFAC Symposium, Swansea, 11-13 July 1988, where a forum was provided for discussion of the latest advances and techniques in the education of control and instrument engineers. Seven major topics were covered to aid lecturers in understanding, developing and presenting systems engineering - control and measurement - as a subject to undergraduate and postgraduate students. The teaching of real-time computer control as a topic and laboratory experiments for both continuous and discrete systems were discussed, as was process control, with the emphasis on providing the student with engineering experience by using scaled-down equipment which would teach practical skills. Included in the Proceedings are papers on measurement and instrumentation, an area felt to be neglected within academic instruction. The development of software tools for systems design within systems engineering was included, as was the exchange of teaching packages and methods between academics, and the education curriculum of systems engineering within developing countries. These Proceedings will prove to be a useful up-to-date guide and reference source for all lecturers and professors involved in curriculum development and the teaching of control and measurement in systems engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Optimization problems were and still are the focus of mathematics from antiquity to the present. Since the beginning of our civilization, the human race has had to confront numerous technological challenges, such as finding the optimal solution of various problems including control technologies, power sources construction, applications in economy, mechanical engineering and energy distribution amongst others. These examples encompass both ancient as well as modern technologies like the first electrical energy distribution network in USA etc. Some of the key principles formulated in the middle ages were done by Johannes Kepler (Problem of the wine barrels), Johan Bernoulli (brachystochrone problem), Leonhard Euler (Calculus of Variations), Lagrange (Principle multipliers), that were formulated primarily in the ancient world and are of a geometric nature. In the beginning of the modern era, works of L.V. Kantorovich and G.B. Dantzig (so-called linear programming) can be considered amongst others. This book discusses a wide spectrum of optimization methods from classical to modern, alike heuristics. Novel as well as classical techniques is also discussed in this book, including its mutual intersection. Together with many interesting chapters, a reader will also encounter various methods used for proposed optimization approaches, such as game theory and evolutionary algorithms or modelling of evolutionary algorithm dynamics like complex networks.
