Abstract :
Because of the perturbations and disturbances of electro-hydraulic servo systems, the normal controller can´t obtain good output responses under various conditions. The sliding mode control (SMC) based on fuzzy logic was presented for the system, and this approach can adjust parameters of reaching law at real time. Simulation results show that the improved system has nice robustness, and it is not sensitive to load variances and external disturbances. This fuzzy sliding mode controller has good dynamic performance, suppresses the undesirable chattering of control signal completely, and provides valuable reference for actual application
