Abstract

In this paper the static characteristics of composite 4-way valve composed of two 3-way 2-position high speed on-off valves or four 2-way 2-position ones are studied. Using this kind of control valve, the electrohydraulic position servo system that is controlled by an 8098 single chip computer is developed. Through the study of frequency characteristics of the servo system the methods of analysis and synthesis the system were also introduced. Its correctness is proved by experiment.
