Book Description
"Hydraulic servoactuators have long been used in industry where high performance precision motion control is required. Because of their precision and ability to generate large forces, applications are numerous in industry. One such application provides cockpit motion for flight simulation. This thesis investigates a new emergency shutdown (abort) scheme for such high performance servo-systems. Because flight simulation involves the motion control of both man and machinery (a mock cockpit in motion), it will be used as the standard by which a safe and effective abort is modeled. The justification for motion abort during actuator operation is unsafe actuator accelerations. In order to protect man and equipment, the operation of critical servosystems, such as flight simulators, must be constantly monitored to detect system malfunctions which might cause personal injury or equipment damage. After any malfunction is detected, the appropriate shutdowm hardware must be signaled to safely take command of the servosystem and bring it to rest. The intent of this thesis was to verify the integrity of a new concept in hydraulic actuator abort, which utilizes the mechanical feedback of actuator acceleration. Once verified, critical design parameters can be further optimized and possible design configurations suggested. The abort system was modeled on a software package called Continuous System Modelling Program (CSMP). The actual abort subsystem proved to work as expected, but when integrated into the flight simulation actuation system, instability was observed. This instability occurred due to extremely large inertial forces acting on relatively large volumes of compressible hydraulic fluid. The spring rate imposed by the hydraulic fluid caused high frequency oscillations, superimposed on the desired steady state behavior, to pass through the entire system. Various loop gains in the model were adjusted to minimize the oscillations, but an additional dampening device would be the likely solution to effectively attenuate the instability. Such a device could be the topic of another thesis."--Abstract.

Book Description
This volume gathers together all the lectures presented at the 6th IEEE Mediterranean Conference. It focuses on the mathematical aspects in the theory and practice of control and systems, including stability and stabilizability, robust control, adaptive control, robotics and manufacturing; these topics are under intense investigation and development in the engineering and mathematics communities. The volume should have immediate appeal for a large group of engineers and mathematicians who are interested in very abstract as well as very concrete aspects of control and system theory.

Book Description
This book covers the fundamental concepts of electrohydraulic (EH) servo systems in detail and also presents the developments about power, quadratic response, and control flexibility of EH servo systems with applications in aircraft/aerospace engineering, mobile equipment, material/structure testing, motion simulators, and strategic defense sectors. Various topics covered in this books are systems and configurations of servo systems, components, applications, design of SISO and MIMO and control options of SISO and MIMO systems. It further includes a chapter on contamination control, fault detection and diagnosis (FDD) of these systems. The detailed working procedures and advice on implementation routines presented in this book will help readers to apply the control models and systems presented so as to make their own servo systems more efficient. The book will be useful for mechanical engineers and professionals involved in the analysis and design of electrohydraulic control systems, especially in advanced hydraulic industries, the aeronautical and space, and automotive industries. It would also be a useful reference for advanced courses in EH systems.
