Perfect tracking control for flight simulator
飞行仿真转台的完全跟踪控制

To deal with the performance limitations for the traditional interpolation and feedforward methods in flight simulator, we introduce the perfect tracking control(PTC) strategy, and study its application on the design of a flight simulator for perfect tracking. We make use of the characteristics of a multirate sampling system to build an exact inverse transfer function matrix model of the flight simulator for realizing the perfect tracking, preventing from the performance limitations brought about by the traditional approximate inverse transfer matrix model and the interpolation algorithm. By the robust internal-loop compensator theory, and based on the analytical expressions of the tracking errors, we prove that the proposed strategy ensures the system with desired tracking accuracy and excellent robustness, even in the existence of modeling errors and disturbances. Results in designing and experimenting in practical systems validate the proposed strategy.
