Friction Compensation Based Acceleration Feedback Control for Flight Simulator
The flight simulator is one kind of servo system with uncertainties and disturbances. To obtain high low-velocity performance and good robustness for the flight simulator, we present a novel robust controller based on the acceleration feedback and Disturbance Observer. Firstly, the plant model and the framework of the novel controller are described. Secondly, the principle and the design process of the acceleration feedback controller are analyzed and expatiated respectively. Finally, simulation results on the flight simulator show that the acceleration feedback controller can compensate nonlinear friction problems and the system performance can be improved. Therefore both robustness and high performance of the flight simulator are achieved. It is an applied technology for the control of servo system, such as the flight simulator.
