Abstract: The flexible simulator and control system is torque servo system to simulate the disturbance of the satellite, which could complete the accurate tracking of the periodic instruction and eliminate the nonlinear disturbance in the system. Based on the mathematical model of the simulator and the nonlinear factors in the operation such as the friction disturbance and the parameter perturbation, adaptive speed controller and adaptive torque controller were designed via introducing the concept of adaptive control. Using Lyapunov stability theory to analyze stability of the designed controller, the controller parameters ranges were got. The experimental results show that compared with the traditional control method, adaptive control can effectively improve the torque precision of the system and satisfy the high precision and variable frequency torque output in the experiment of the flexible simulator.
