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 time-delay system. The aim of the control design is to reduce the tracking error as much as possible for all bounded reference inputs and guarantee H∞ performance. The advantage of the proposed tracking control design is that only a simple fuzzy controller is used in the approach without feedback linearization technique and complicated adaptive scheme. Simulation example is given to testify the validity and efficiency of the proposed method.
