N2 - Electro-hydraulic proportional servo valve (EHPSV) is a typical precision hydraulic component, widely used in construction machinery, aircraft, ships and other important equipment. When the electro-hydraulic proportional servo valve is working, the pollution particles in the hydraulic oil will cause erosion and wear of the valve element and seriously affect the control precision of the valve. In addition, the hydraulic system is a typical nonlinear system, if the traditional PID controller is used for control, the control precision of the system can not be guaranteed. In this paper, the typical valve controlling cylinder system in hydraulic system is taken as the research object. An ARC controller is designed to control the system, and an erosion wear prediction model is established by finite element simulation to control the valve-controlled cylinder system with high-quality flow compensation under the ARC control architecture. In this paper, the modeling and simulation of valve controlling cylinder system are carried out by MATLB/Simulink. The results show that the adaptive robust controller with erosion wear prediction model can effectively improve the control precision of proportional servo valve.
