In this paper, a stochastic observer is proposed, which can make the estimation error dynamics to be stochastically asymptotical stable and impulse-free. Moreover, an integrated estimation and feedback control mechanism is presented, which can make both the state and error dynamics stochastically asymptotical stable and impulse-free. Simulated results demonstrate the efficiency of the proposed approach...
A novel fuzzy-observer-design approach is presented for Takagi-Sugeno fuzzy models with unknown output disturbances. In order to decouple the unknown output disturbance, an augmented fuzzy descriptor model is constructed by supposing the disturbance to be an auxiliary state vector. A fuzzy state-space observer is next designed for the augmented fuzzy descriptor system, and the simultaneous estimates...
In this paper, we focus all attention on finding a solution to the problem how to reduce the difficulty of TS fuzzy system controller design. In other words, our goal is to obtain fewer inequalities in LMIs which is one of the most important tools for fuzzy system controller design. By constructing an augment system, the problem of controller design is turned into stability problem of a fuzzy descriptor...
