Abstract

In this paper, a novel adaptive inverse controller with H∞ tracking performance for uncertain nonlinear systems was proposed to attenuate the effects caused by unmodeled dynamics, disturbances and approximate errors. The control law and the update law were derived by inverse control method and the uncertain parameter was tuned by adaptive approach Then the H∞ tracking design technique was incorporated into the adaptive inverse control scheme to derive the control law so that the derived controller was robust with respect to unmodeled dynamics, disturbances and approximate errors. Compared with traditional methods, the proposed approach not only assures closed-loop stability, but also guarantees a H∞ tracking performance for the overall system based on relaxed assumption without prior knowledge on the upper bound of the lumped uncertainties. Simulation results have shown validity of the proposed control law.
