Closed Loop Electrohydraulic Systems Manual Book

This text was designed to help people involved with closed-loop electrohydraulic control systems. Because the discussion of fundamental principles of amplifiers, ramp generators and comparators requires a working knowledge of electronics, the reader will learn about voltage, current, resistance and capacitance in DC circuits. The manual covers the operation of open and closed-loop servo valves and proportional valve systems, and design considerations such as valve sizing, actuator selection and feedback transducers. It was prepared assuming the reader has a solid understanding of fluid power concepts.
