Abstract

In this article a fuzzy controller is designed for a chaotic model whose structure is represented by the Takagi-Sugeno model. Using the T–S model of chaotic systems, the control algorithm is developed based on parallel distributed compensator concept and the Lyapunov method [1] is used to carry out stability analysis of a real system structure. In terms of PDC fuzzy control theory, the whole control sub-systems fuzzy control can be achieved by each subsystems control. The simulation results shows the effectiveness and feasibility of the method to stabilize a Lorenz system.
