Book Description
In a variety of machinery, working members are driven by hydraulic cylinders. Such hydraulic systems are used to control multiple functions, such as raising and lowering the member, tilting and rotating the member about an axis, and sliding the member fore and aft. Flow-control valves are used in these hydraulic systems to control rate of flow from one part of the system to another. A proportional-priority-pressure compensating type of flow-control valve is used to proportionally divide the pump flow between the branches of the circuit based on their requirement. The valve uses a pressure compensator for accurate flow rate control. The pressure compensator maintains a constant pressure drop across the main spool valve. The pressure compensator is an integral part of the flow-control valve. In this thesis, a model and stability analysis for the pressure compensator is presented.

Book Description
Drives and Control for Industrial Automation presents the material necessary for an understanding of servo control in automation. Beginning with a macroscopic view of its subject, treating drives and control as parts of a single system, the book then pursues a detailed discussion of the major components of servo control: sensors, controllers and actuators. Throughout, the mechatronic approach – a synergistic integration of the components – is maintained, in keeping with current practice. The authors’ holistic approach does not preclude the reader from learning in a step-by-step fashion – each chapter contains material that can be studied separately without compromising understanding. Drives are described in several chapters according to the way they are usually classified in industry, each comprised of its actuators and sensors. The controller is discussed alongside. Topics of recent and current interest – piezoelectricity, digital communications and future trends – are detailed in their own chapters.

Book Description
A practical introductory guide to the principles of process measurement and control. Written for those beginning a career in the instrumentation and control industry or those who need a refresher, the book will serve as a text or to supercede the mathematical treatment of control theory that will continue to be essential for a well-rounded understanding. The book will provide the reader with the ability to recognize problems concealed among a mass of data and provide minimal cost solutions, using available technology.

Book Description
Fluid power systems are manufactured by many organizations for a very wide range of applications, embodying different arrangements of components to fulfill a given task. Hydraulic components are manufactured to provide the control functions required for the operation of a wide range of systems and applications. This second edition is structured to give an understanding of: • Basic types of components, their operational principles and the estimation of their performance in a variety of applications. • A resume of the flow processes that occur in hydraulic components. • A review of the modeling process for the efficiency of pumps and motors. This new edition also includes a complete analysis for estimating the mechanical loss in a typical hydraulic motor; how circuits can be arranged using available components to provide a range of functional system outputs, including the analysis and design of closed loop control systems and some applications; a description of the use of international standards in the design and management of hydraulic systems; and extensive analysis of hydraulic circuits for different types of hydrostatic power transmission systems and their application.

Book Description
This work introduces the principles of water hydraulics technology and its benefits and limitations, and clarifies the essential differences between water and oil hydraulics. It discusses basic components and systems, including hydraulic power generators (pumps), hydraulic control components or modulators (valves), hydraulic transmission lines (tubes, hoses and fittings) and hydraulic actuators (single- or double-acting cylinders and rotary motors). A listing of water hydraulics components/systems manufacturers is provided.
