Liu, M.Cao, X.Shi, P.2013-06-202013-06-202013IEEE Transactions on Fuzzy Systems, 2013; 21(2):221-2291063-67061941-0034http://hdl.handle.net/2440/78424This paper deals with the problem of fault estimation and fault-tolerant control for Takagi-Sugeno (T-S) fuzzy stochastic systems with sensor failures, where the system under consideration contains Itô-type stochastic disturbances. A new robust observer technique is presented to obtain the estimates of the system states and the sensor faults simultaneously, and a fuzzy fault-tolerant control scheme is developed to guarantee the closed-loop system to be exponentially stable in mean square. Sufficient conditions are obtained for the existence of admissible controllers, and it is shown that the reachability of the sliding-mode dynamics can be guaranteed under the proposed control techniques. Finally, a numerical example is provided to illustrate the effectiveness and applicability of the theoretic results obtained.en© 2012 IEEEFault estimation, fault-tolerant control (FTC), Itô stochastic system, sensor fault, sliding-mode observer, Takagi– Sugeno (T–S) fuzzy systemJournal article002012663910.1109/TFUZZ.2012.22094320003170014000032-s2.0-8487569981820540Shi, P.
