Control Of Fluid Power

Most of the existing books in this field discuss the hydraulic and pneumatic systems in concentrating on the design and components of the system without going deep enough into the problem of dynamic modelling and control of these systems. This book attempts to compromise between theoretical modelling and practical understanding of fluid power systems by using modern control theory based on implementing Newton's second law in second order differential equations transformed into direct relationships between inputs and outputs via transfer functions or state space approach.

Fluid Power Circuits and Controls: Fundamentals and Applications, Second Edition, is designed for a first course in fluid power for undergraduate engineering students. After an introduction to the design and function of components, students apply what they’ve learned and consider how the component operating characteristics interact with the rest of the circuit. The Second Edition offers many new worked examples and additional exercises and problems in each chapter. Half of these new problems involve the basic analysis of specific elements, and the rest are design-oriented, emphasizing the analysis of system performance. The envisioned course does not require a controls course as a prerequisite; however, it does lay a foundation for understanding the extraordinary productivity and accuracy that can be achieved when control engineers and fluid power engineers work as a team on a fluid power design problem. A complete solutions manual is available for qualified adopting instructors.

Detailed coverage of the concepts of Hydraulics, Pneumatic, Control valves, Lever systems. Objective type questions included in each chapter. Detailed study of each and every topic in the chapter.

This text-book provides an in-depth background in the field of Fluid Power, It covers Design, Analysis, Operation and Maintenance. The reader will find this book useful for a clear understanding of the subject and also to assist in the selection and troubleshooting of fluid power components and systems used in manufacturing operations, providing a systematic summary of the fundamentals of hydraulic power transmission. This book discusses the main characteristics of hydraulic drives and their most important types in a manner comprehensible even to newcomers of the subject. This book covers a broad range of topics in the field, including: physical properties of hydraulic fluids; energy and power in hydraulic systems; frictional losses in hydraulic pipelines; hydraulic pumps, cylinders, cushioning devices, motors, valves, circuit design, conductors and fittings; hydraulic system maintenance; pneumatic air preparation and its components; and electrical controls for fluid power systems. It provides everything you need to understand the fundamental operating principles as well as the latest maintenance, repair and reconditioning techniques for industrial oil hydraulic systems. Better understanding of the material is promoted by the sample solutions to various mathematical problems given in each chapter. A number of photographs and illustration have been attached to reflect current "Fluid Power system".

This exciting reference text is concerned with fluid power control. It is an ideal reference for the practising engineer and a textbook for advanced courses in fluid power control. In applications in which large forces and/or torques are required, often with a fast response time, oil-hydraulic control systems are essential. They excel in environmentally difficult applications because the drive part can be designed with no electrical components and they almost always have a more competitive power/weight ratio compared to electrically actuated systems. Fluid power systems have the capability to control several parameters, such as pressure, speed, position, and so on, to a high degree of accuracy at high power levels. In practice there are many exciting challenges facing the fluid power engineer, who now must preferably have a broad skill set.
