Abstract :
The mathematical model of the flight simulator servo system was analyzed and the discrete sliding mode control (DSMC) was proposed, the reaching law of DSMC with Kalman filter was introduced to enhance the control character. The simulation shows the DSMC without filter has the big chattering and can influenced by disturbance, the DSMC with filter drives system state trajectories to arrive at the switch band in limit time and thereafter maintain in the switch band and the chattering around sliding surface is reduced effectively, also the tracking performance is satisfactory for turntable system.
