Adaptive Backstepping Control for Flight Simulator

The flight simulator is a kind of servo system with uncertainties and disturbances. To obtain high performance and good robustness for the flight simulator, we present an adaptive backstepping controller, which is robust to the parameter uncertainties and load disturbances. First, the model of the flight simulator with parameter uncertainties and load torque disturbances is proposed based on experiment test. Second, the design procedure of the adaptive backstepping controller is described and analyzed. The parameter update law and control law are designed based on Lyapunov stability theorem. Simulation results clearly show that the proposed control scheme can track the position reference signal successfully under parameter uncertainties and load torque disturbance
