This book was released on 1988 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydraulic servo mechanisms combine hydraulic power and feedback techniques to achieve rapid, accurate regulation. In recent years with the development of electronic technology, electro-hydraulic servo control systems have found more usage in industry and military systems of all types. This thesis deals with the mathematical modelling and computer simulation of an electro-hydraulic servovalve controlled motor for both speed and position schemes. As a preliminary investigation, these systems are simplified to achieve insight into the physical problem. In the speed control scheme, linear equations are employed to describe the system. However in the position control scheme, the equations describing the system are nonlinear. Control theory is used to analyse the system and thereafter simulation programs for both speed control and position control are designed to investigate dynamic behaviour and simulated results of each system are shown graphically. Some improved control concepsions are also given in this thesis. In speed control scheme, a slope command signal is utilised instead of a sudden change of command signal, and this improvement achieves the reduction of the system overshoot and oscillation. In position control, which is a variable torque system, so called 'equigain' and 'varigain' control schemes are established to improve the accuracy of trajectory control. Finally recommendations for further work are presented with references for initiating these enquires.

This book was released on 2013-02-12 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the basic working principle and the mechanical construction of automatic transmissions has not changed significantly, increased requirements for performance, fuel economy, and drivability, as well as the increasing number of gears has made it more challenging to design the systems that control modern automatic transmissions. New types of transmissions—continuously variable transmissions (CVT), dual clutch transmissions (DCT), and hybrid powertrains—have presented added challenges. Gear shifting in today’s automatic transmissions is a dynamic process that involves synchronized torque transfer from one clutch to another, smooth engine speed change, engine torque management, and minimization of output torque disturbance. Dynamic analysis helps to understand gear shifting mechanics and supports creation of the best design for gear shift control systems in passenger cars, trucks, buses, and commercial vehicles. Based on the authors’ graduate-level teaching material, this well-illustrated book relays how the fundamental principles of hydraulics and control systems are applied to today’s automatic transmissions. It opens with coverage of basic automatic transmission mechanics and then details dynamics and controls associated with modern automatic transmissions. Topics covered include: gear shifting mechanics and controls, dynamic models of planetary automatic transmissions, design of hydraulic control systems, learning algorithms for achieving consistent shift quality, torque converter clutch controls, centrifugal pendulum vibration absorbers, friction launch controls, shift scheduling and integrated powertrain controls, continuously variable transmission ratio controls, dual-clutch transmission controls, and more. The book includes many equations and clearly explained examples. Sample Simulink models of various transmission mechanical, hydraulic and control subsystems are also provided. Chapter Two, which covers planetary gear automatic transmissions, includes homework questions, making it ideal for classroom use. In addition to students, new engineers will find the book helpful because it provides the basics of transmission dynamics and control. More experienced engineers will appreciate the theoretical discussions that will help elevate the reader’s knowledge. Although many automatic transmission-related books have been published, most focus on mechanical construction, operation principles, and control hardware. None tie the dynamic analysis, control system design, and analytic investigation of the mechanical, hydraulic, and electronic controls as does this book.
