Abstract :
For flight motion simulator servo system, this paper presents a kind of robust discrete sliding mode controller based on disturbance observer. The entire system is composed of two parts: one is the design of disturbance observer and the other is the design of discrete sliding mode controller. Sliding mode controller (SMC) is a special nonlinear control strategy, which has strong robustness against parameter variations, load disturbances and uncertainty of system, but the chattering produced by sliding mode control limits its application to the practical system. In this paper, by using disturbance observer technology, the external disturbances can be compensated and the SMC control law can be used successfully, and the chattering can be effectively alleviated. The proposed controller is adopted in flight motion simulator servo system. Simulation and real system experiment results confirm the effectiveness of the proposed control method.
