The control of flexible robotic arm with uncertainty such as variable payload, joint angle frictional torque etc., is an interesting and important problem; Here we consider control of joint angles and stabilization of the flexible modes caused by the manuever of robotic arm by two methods. These are: (i) Variable Structure control and (ii) Nonlinear Ultimate Boundedness control. Nonlinear Ultimate Boundedness control is a continuous control wherein the joint angle tracking error is uniformly ultimately bounded in the closed-loop system; Analytical derivations of these two schemes are presented. A control logic is included which switches the stabilizer when the joint angle trajectory enters a specified neighborhood of the terminal state; Extensive simulations were carried out for several conditions of uncertainty and the results are presented.
