Design of dead beat controller for electrohydraulic speed servo system

Abstract

This paper deals with the control methods of electro-hydraulic speed servo control system with large power which is used in the aeroplane engine simulating rig. In order to obtain the fast response characteristics in the system, the dead beat control method combined with the fuzzy control is adopted by means of the simplified first-order and second-order mathematical models are established, and control experiments is carried out. The experimental results show that the satisfactory response characteristics are obtained by using the dead beat control method combined with the fuzzy control with the second-order model.
