A novel design of fuzzy tracking control for nonlinear time-delay systems

A robust tracking control technique for nonlinear time-delay systems based on fuzzy T-S model is developed. Fuzzy T-S model with parametric uncertainties is employed to represent a nonlinear system of the plant to be controlled. The aim of the control design is to make the tracking error hundred reference inputs and to guarantee H_∞ performance of the control system. The proposed tracking control design has the advantage that only a simple fuzzy controller is used within an approach without employing feedback lincarization and a complicated adaptive scheme. By means of the proposed method, the filmy tracking control design problem is parameterized in terms of a linear matrix inequality problem. The linear matrix inequality problem is thensolved efficiently by using a convex optimization technique. Simulation example given to test the validity and efficiency of ihc proposed method.
