Abstract

According to the work characteristics of the electromechanical actuator, a control scheme of direct DC electromechanical actuator based on discrete-time variable structure controller is designed. The effect of hinge moment is considered in the mathematical model, and the coefficients of its transfer function are appropriately amended. The effect of the three parameters in the design of discrete-time sliding mode is analyzed and the system trajectory can be maintained in the sliding mode area. The simulation results indicate that the system has become the global optimal one.
