Abstract

This paper investigates the tracking problem of nonholonomic mobile robots. A control structure combining a kinematic controller and a dynamic controller based on nonlinear feedback control plus fuzzy compensator is presented. The fuzzy compensator, whose parameters are tuned on-line, is employed to approximate the total uncertainty including the structured and unstructured uncertainties due to the universal approximation property of fuzzy logic systems. The stability of the proposed approach is guaranteed by the Lyapunov theory. Simulation results show the efficiency of the proposed approach.
