Abstract

Electro-Hydrostatic Actuator (EHA) has developed rapidly in airborne flight control systems due to its compact structure, high energy efficiency and easy control. However, because of the strong nonlinearity of EHA system and external uncertainties, simple PID control cannot achieve the ideal control requirements. This paper proposes a composite control system that controls the actuator cylinder position with sliding mode and motor speed with PID. Sliding-mode position controller structure is designed, and an adaptive genetic algorithm is used to optimize the composite control parameters. The simulation results show that the optimized sliding mode-PID composite control can eliminate the overshoot, suppress the external interference and achieve the precise control of EHA position.
