This paper investigates the problem of fault detection for Takagi-Sugeno (T-S) fuzzy discrete systems in finite-frequency domain. By means of the T-S fuzzy model, both a fuzzy fault detection filter system and the dynamics of filtering error generator are constructed. Two finite-frequency performance indices are introduced to measure fault sensitivity and(More)
The problem of robust sliding mode control (SMC) for uncertain time-delay systems is investigated in this paper. Based on novel ideal of virtual state feedback control, a delay-independent sufficient condition is developed for the design of a robust stable sliding mode plane in term of linear matrix inequalities (LMI). A SMC controller is derived to ensure(More)
