Abstract
An anti-disturbance fault tolerant control (FTC) based on disturbance observer scheme is considered for a class of stochastic systems with faults and multiple disturbances in this paper. The disturbances are divided into two parts. One represents the stochastic disturbance with partial-known information which is formulated by an exogenous system. The other is independent Wiener process. A stochastic disturbance observer is designed to estimate exogenous disturbance using pole placement. And a composite fault diagnosis observer with disturbance observer is constructed to diagnose faults. Furthermore, a composite fault-tolerant controller is proposed to compensate modeled disturbance and accommodate faults. Finally, a simulation example is given to demonstrate the feasibility and effectiveness of the proposed scheme.
