Abstract: | This paper investigates the fuzzy control problem of a class of nonlinear continuous-time stochastic systems with achieving
the 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 that are represented by the Takagi-Sugeno
(T-S) fuzzy models. Based on the Lyapunov criteria, the Linear Matrix Inequality (LMI) technique is used to synthesize the
observer feedback fuzzy controller design such that the closed-loop system satisfies stability and passivity constraints,
simultaneously. Finally, a numerical example is given to demonstrate the applicability and effectiveness of the proposed design
method. |
