In this paper, robust H∞ control for Takagi-Sugeno (T-S) fuzzy system with probabilistic interval timevarying state delay is considered. By considering the probability distribution properties of the time-varying delay taking values between the two given intervals, employing the parallel distributed compensation approach, a new state-space model whose system matrix contains random variables is proposed...
Fuzzy H∞ excitation controller is presented for a single machine infinite-bus system. Firstly, the model of a single machine infinite-bus system with an excitation controller is changed to a linear system form based on the traditional method. A series of partial dynamic model are educed from the linear system. Then the degree of membership function is presented, based on which, the overall dynamic...
The delay-dependent robust Hinfin control problem for a class of nonlinear time-delay system is investigated in this paper. An uncertain Takagi-Sugeno (T-S) fuzzy model is adopted for representing a nonlinear system with time-varying delay, in which the modeling errors are absorbed in the uncertain part. The design method of delay-dependent robust Hinfin controller is firstly established via the...
This paper deals with the guaranteed cost control of a class of Takagi-Sugeno (T-S) fuzzy systems with norm-bounded parametric uncertainties via the piecewise quadratic Lyapunov function (PQLF). A linear quadratic cost function is considered as a performance index of closed-loop fuzzy systems. Then, based on the PQLF approach, a robust optimal guaranteed cost control law for stabilization of closed-loop...
This paper deals with the class of continuous-time uncertain stochastic fuzzy systems with norm bounded uncertainties. A model-based fuzzy stabilization design utilizing the concept of the so-called parallel distributed compensation (PDC) is employed to stochastically stabilize the class of systems under consideration. LMI-based sufficient conditions are developed to synthesize the state feedback...
