Abstract :
In this paper, fuzzy modeling techniques based on Takagi-Sugeno (T-S) fuzzy model are proposed to control the generalized Lienard system. The stability analysis of this fuzzy control model is performed using Lyapunov theorem. This paper proves that if the derivative of Lyapunov function is negative semi-defined for each fuzzy rule, then the controlled Lienard system is asymptotic stable in the Lyapunov sense. The stability theorem present in this paper assures sufficient conditions for the stability of the Lienard system controlled by fuzzy logic controller (FLC). Sections 5 and 6 contains an illustrative example that describes an application of the method of the stability analysis.
