Abstract

Robust adaptive control of a 6-DOF space robot with flexible panels are investigated in this paper. Dynamic model of the robot system is present firstly. Based on computed torque control method, a robust adaptive controller considering the uncertainties of the robot system is proposed to achieve the trajectory tracking and to suppress the elastic vibrations of the panels, and the stability of the controller is guaranteed by the Lyapunov stability theory. The trajectory tracking is performed by using the designed controller. Simulation results indicate that the designed controller can effectively make the robot system with uncertain parameters reach a desired target and the elastic vibration of the panels may be suppressed simultaneously.
