Polynomial fuzzy control of Multi-scroll Chen chaotic system via sum-of-squares approach

This paper presents the design and simulation results considering the use of polynomial fuzzy control for stabilization of multi-scroll Chen chaotic system. The chaotic system is represented in the polynomial fuzzy model form and less conservation stability conditions are proposed. The controller here designed is obtained by solving the sum-of-squares constraints via SOSTOOLS. Simulation results show the effectiveness of the proposed controller design method.
