“…Therefore, more efforts are needed to efficiently estimate the state and fault information. In this study, unlike the conventional descriptor model [40], the nonsingular fault dynamic models of f a (t) and f s (t) in (5) and (6) are to be embedded in the augmented system with T-S fuzzy system in (2). In this situation, the conventional Luenberger observer could be employed to precisely estimate the state variables and actuator and sensor fault signals to efficiently compensate the effect of fault signals and external disturbance for the FTC design.…”

This paper deals with the problem of proportional-difference observer design for singular systems in the discrete-time domain. Several necessary and sufficient conditions for the existence and convergence of the proposed observer are given and proved. Without using any additional transformations, a necessary and sufficient condition for the solvability of this problem is obtained in terms of linear matrix inequalities. The explicit expression of desired observer is also given. Furthermore, an extension to a class of nonlinear singular systems with Lipschitz constraints is investigated. Finally, a practical example and a numerical one are simulated to illustrate the effectiveness of the proposed approaches.

“…Passive fault-tolerant control (PFTC) [1][2][3] has been studied by a large number of scholars due to its advantages of simple design. In addition, the active fault-tolerant control (AFTC) [4][5][6] method, which can design the controller online for each fault, is also discussed.…”

In this paper, a hybrid fault-tolerant control method with off-line design and online scheduling is proposed for NCS with actuator faults, random delay, and external finite energy disturbance. The problem of less conservatism of robust generalized H2/H∞ hybrid fault-tolerant control is studied. Firstly, a closed-loop fault model of the system with random delay parameters was established according to the Bernoulli 0-1 distribution; all possible prior faults are divided into a few intervals according to certain rules, and then an interval fault-tolerant controller is designed off-line according to the prior faults of each interval. Secondly, when the fault is estimated online, the corresponding interval fault-tolerant controller is called through the scheduling mechanism to achieve rapid fault tolerance of prior faults within the interval and mitigate the impact of other faults within the interval, which provides a guarantee for subsequent safe reconstruction control. Finally, the effectiveness of the proposed method is verified by Matlab simulation.
