A study of a robust fuzzy controller for perturbed nonlinear systems

In this paper, a fuzzy logic controller (FLC) for a nonlinear system with uncertain perturbation is proposed. Based on the Lyapunov synthesis approach, we construct the FLC not only to stabilize the perturbed nonlinear system but also to guarantee a prescribed H[subscript infinity] norm bound of the...

Description
Summary:In this paper, a fuzzy logic controller (FLC) for a nonlinear system with uncertain perturbation is proposed. Based on the Lyapunov synthesis approach, we construct the FLC not only to stabilize the perturbed nonlinear system but also to guarantee a prescribed H[subscript infinity] norm bound of the closed-loop transfer function from the disturbance to the controlled output. A given example illustrates the availability of the proposed design method. [PUBLICATION ABSTRACT]
