Fuzzy modeling and control of a class of simple pendulum system based on robust technology

This paper is concerned with the problem of fuzzy modeling in the T-S fuzzy systems. In order to obtain relative simple T-S fuzzy model, combined with the traditional linearization approximation method on the fuzzy modeling. It deals the nonlinear term of unable to approximate with the same method of the uncertainties of processing, so that it could design the uncertainty T-S fuzzy system with the robust technology. Although the presented modeling method will obtain larger dimension matrix inequality, it can be decreased the number of fuzzy rules. The matrix inequality dimension and the number of fuzzy rules would be discussed in a simulation example based on the comparison of control calculation burden.
