Generating Li—Yorke chaos in a stable continuous-time T—S fuzzy model via time-delay feedback control

This paper investigates the chaotification problem of a stable continuous-time T—S fuzzy system. A simple nonlinear state time-delay feedback controller is designed by parallel distributed compensation technique. Then, the asymptotically approximate relationship between the controlled continuous-time T—S fuzzy system with time-delay and a discrete-time T—S fuzzy system is established. Based on the discrete-time T—S fuzzy system, it proves that the chaos in the discrete-time T—S fuzzy system satisfies the Li—Yorke definition by choosing appropriate controller parameters via the revised Marotto theorem. Finally, the effectiveness of the proposed chaotic anticontrol method is verified by a practical example.
