摘要：
A discrete fuzzy sliding mode variable structure controller was studied and designed for a class of electro-hydraulic servo system by means of the combination of sliding mode control theory and fuzzy control theory.Designed based on the exponential reaching law,parameter ε of conventional sliding mode controller is the key factor of system chattering,and is proportional to it as well.In view of this,fuzzy control theory was introduced into the design to ensure the real-time adjusting of parameter ε.Simulation results show that the system chattering is eliminated perfectly,and the dynamic performance of the control system is improved effectively.
