Abstract

In this paper, a novel robust adaptive controller is proposed to simultaneously cope with the unknown nonlinear backlash, friction and dynamic uncertainties in the 3-DOF robotic head system. Inverse backlash compensation with on-line backlash parameter estimation and model-based friction compensation with off-line Stribeck friction identification are incorporated into this robust adaptive scheme. By parametrically linearizing the system dynamic equation, dynamic uncertainties are estimated. This controller is mathematically derived by using Lyapunov stability analysis. Simulation results are presented to show the high tracking performance of the controller.
