Considering friction moment disturbances and system parameter perturbations during the control of flight simulator,a robust controller based on quadratic stability is proposed.By analyzing the basic principle and theory of quadratic stability,the state feedback controller and robust PID controller based on quadratic stability for a flight simulator system are designed.Simulation result shows that the controllers based on quadratic stability overcome the friction moment disturbances and inertia moment perturbations of the flight simulator system successfully.The corner precision control and dynamic order of the flight simulator are perfectly realized,so the proposed controller is suitable for robust control of high-precision flight simulator system.
