EHA position system simulation based on fuzzy sliding mode control

The electro-hydrostatic actuator (EHA) is a highly integrated hydraulic actuation system, the traditional control method is difficult to achieve a good control effect in the case of highly nonlinear and external disturbances. In order to improve the control effect of EHA and improve the performance of hydraulic servo system, a SMC-Fuzzy controller is designed. The simulation results show that the SMC-Fuzzy controller has a better tracking performance than traditional PID controller, besides due to the application of Fuzzy rule, the system control input is more smooth, and reduce system chattering.
