Description
Summary:The 3-axis flight table is an important device and a typical high performance position and speed servo system used in the hardware in the loop simulation of flight control system. Friction force and uncertainty are the main characteristics in the 3-axis flight table servo system. Based on the description of dynamic and static model of a nonlinear Stribeck friction model, and taking account of the practical uncertainties of 3-axis flight table servo system, the QFT controller is designed. Simulation and real-time results are presented.
