Flight simulator is an important application in the field of aerospace as semi-physical simulation equipment. As it requires supreme control precision and stability, it is especially important to search the performance assessment of flight simulator servo system. The traditional researches on flight simulator control performance index is more about dynamic output tracking features but few on input characteristics and effects. Based on Linear Quadratic Gaussian (LQG) performance benchmark, this paper makes analyses on high precision flight simulator in three kinds of controller while considering the influences of input and output signals’ effect on controllers. After processing the input and output data, combined with the linear fitting method, we can obtain LQG performance tradeoff curve. Through comparing the controller’s actual performance with the optimal performance, we’ll gain the controller’s control performance index and its potential.
