This paper addresses the problem on sensor fault estimation and fault-tolerant control for a class of Takagi-Sugeno Markovian jump systems, which are subjected to sensor faults and partially unknown transition rates. First, the original plant is extended to a descriptor system, where the original states and the sensor faults are assembled into the new state vector. Then, a novel reducedorder observer...
In this paper, the problems of observer-based sliding mode control for a class of nonlinear system are investigated via Takagi-Sugeno (T-S) fuzzy approach. By using the T-S model as the design model, an adaptive sliding mode observer is first constructed to estimate the states of the original nonlinear system without knowing any information of the actuator fault. And then, a sliding mode surface in...
