Abstract:This paper investigates the fuzzy control problem of nonlinear continuous-time stochastic fuzzy systems with passivity performance. A model-based observer feedback fuzzy control utilizing the concept of so-called parallel distributed compensation (PDC) is employed to stabilize the class of nonlinear stochastic systems. Based on Lyapunov stability theory, the Linear Matrix Inequality (LMI) technique is used to synthesize the observer and the state feedback controller that stabilize the nonlinear stochastic fuzzy system. Finally, a numerical example is given to demonstrate the effectiveness of the proposed design method.
