Synthesis of Fuzzy Tracking Control for Nonlinear Time-Delay Systems

A robust tracking fuzzy control technique for nonlinear time-delay systems based on fuzzy T-S model is proposed. The fuzzy T-S system model with parametric uncertainties is employed to represent a nonlinear time-delay plant. The control design synthesis is aimed to reduce to negligible small the tracking error for all bounded reference inputs and to guarantee H_infin performance. The advantage of proposed tracking control design is only a simple fuzzy controller designs are employed. By means of the proposed method, the fuzzy tracking control design problem is parameterized in terms of a linear matrix inequality problem, which can be efficiently solved using any convex optimization techniques. The example of trucking control for the benchmark truck-trailer system is given to demonstrate the efficiency as well as the validity of the proposed technique.
