Abstract�� ��To design the robust control system for flight simulator with large parameter uncertainty, quantitative feedback theory (QFT) was employed. The principle and design process of QFT were presented. The feedback controller and prefilter were designed using QFT, which make up of the control system of a certain flight simulator. The experiment result shows that the system keeps up perfect tracking performance when the loads of the flight simulator are changed. It indicates robustness of the system. The comparison with PID control demonstrates that QFT control is able to reject the friction nonlinearity. The anti-disturbance ability of QFT is very good. The application to flight simulator of QFT is successful. It shows the engineering value of the control method.
