| Abstract: | The output tracking problem for a two-DOF robot manipulator with uncertain payload is considered in this paper. By employing input/output feedback linearization approach and Lyapunov method, a design method of robot robust output tracking controller is proposed based on the upper-bounds of the uncertainties. The proposed controller guarantees that the system output can track the desired output with exponential law and all states of the obtained closed-loop system are uniformly ultimately bounded. Moreover, the developed controller is easy to compute and implement. Simulations show that the given method is practical and effective. |
