【Abstract】 Aiming at the major sources of uncertainties in the mechanical motion control system such as nonlinear friction, inertia and external disturbances, a novel robust adaptive tracking controller is designed using backstepping method. The exponentially stable of the controller and the tracking error being freely adjusted are proven using Lyapunov stability theory. The results of simulation and experiments are presented to demonstrate the controller’s high accuracy performance and over conventional PD controller.更多还原
