Book Description
Force and motion control systems of varying degrees of sophistication have shaped the lives of all individuals living in industrialized countries all over the world, and together with communication technology are largely responsible for the high standard ofliving prevalent in many communities. The brains of the vast majority of current control systems are electronic, in the shape of computers, microprocessors or programmable logic controllers (PLC), the nerves are provided by sensors, mainly electromech anical transducers, and the muscle comprises the drive system, in most cases either electric, pneumatic or hydraulic. The factors governing the choice of the most suitable drive are the nature of the application, the performance specification, size, weight, environ mental and safety constraints, with higher power levels favouring hydraulic drives. Past experience, especially in the machine tool sector, has clearly shown that, in the face of competition from electric drives, it is difficult to make a convincing case for hydraulic drives at the bottom end of the power at fractional horsepower level. A further, and frequently range, specifically overriding factor in the choice of drive is the familiarity of the system designer with a particular discipline, which can inhibit the selection of the optimum and most cost-effective solution for a given application. One of the objectives of this book is to help the electrical engineer overcome his natural reluctance to apply any other than electric drives.

Book Description
The book serves as a unique integrated platform, which not only describes the design methodology of electro-hydraulic actuation systems but also provides insights into the design of the servo valve, which is the most important component in the system. It presents a step-by-step design process, comparative tables, illustrative figures, and detailed explanations. The book focuses on the design and testing of electro-hydraulic actuation systems, which are increasingly being used in motion control applications, particularly in those where precision actuation at high operational rates is of prime importance. It describes in detail the design philosophy of such high-performance systems, presenting a system used as a physical test setup together with experimental results to corroborate the calculations. Of particular interest are the electro-hydraulic servo valves that form the heart of these actuations. These valves are complex and not much data is available in open literature due to OEM propriety issues. In this context, the book discusses the elaborate mathematical models that have been derived and an approach to validate the mathematical models with test results. Presenting the complex methodology in simple language, it will prove to be a valuable resource for students, researchers, and professional engineers alike.

Book Description
Nonlinear Control Techniques for Electro-Hydraulic Actuators in Robotics Engineering meets the needs of those working in advanced electro-hydraulic controls for modern mechatronic and robotic systems. The non-linear EHS control methods covered are proving to be more effective than traditional controllers, such as PIDs. The control strategies given address parametric uncertainty, unknown external load disturbance, single-rod actuator characteristics, and control saturation. Theoretical and experimental validations are explained, and examples provided. Based on the authors' cutting-edge research, this work is an important resource for engineers, researchers, and students working in EHS.
