A discrete model reference sliding mode controller with a disturbance compensator and its application to flight simulator

As for parameters fluctuating, uncertainties caused by external disturbance and friction, the nonlinearity of the flight simulator turntable servo system, a discrete model reference sliding mode control theme combining with adaptive method and decoupled disturbance compensator is presented, and the globally asymptotically stability of the system is proved. The simulation results verified that the proposed control method can restrain the uncertainties and external disturbance of the flight simulator servo system efficiently assuring the dynamic tracking performance and strong robustness at a long range frequency.
