A Takagi-Sugeno fuzzy-model-based modeling method

In this paper, a novel fuzzy modeling method is developed for a class of nonlinear system. The idea comes from the concepts of the Takagi-Sugeno (T-S) fuzzy modeling technique, and this method is especially suitable for the nonaffine nonlinear system. Firstly, an inverted pendulum mounted on motor-driven cart is illustrated to demonstrate the validity of modeling result. Besides this example, a nonaffine nonlinear system is illustrated to explain the proposed modeling scheme is more suitable to model the nonaffine nonlinear system into a T-S fuzzy system than some conventional fuzzy modeling schemes.
