Research on robust tracking control based PTC for flight simulator

The flight simulator is one kind of servo system with uncertainties and disturbances. To obtain high tracking performance and good robustness for the flight simulator, we present robust tracking control based perfect tracking controller(PTC) which realizes no magnitude error and phase error for flight simulator during working in a wide frequency range. Firstly, system model of fight simulator is described and correlative problems are proposed. Secondly, the PTC controller is introduced and expatiated. Finally, simulation results of the flight simulator show that the output can achieve perfect tracking of the given position reference signal and the aberration of velocity response based on PTC controller is overcome. Therefore tracking robustness of the flight simulator are achieved. It is an applied tracking technology for the control of servo system, such as the flight motion simulator.
