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. 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.
