Hybrid Robust H2Hxe2x88x9e FaultTolerant Control with Random Delay NCS In this paper, a hybrid faulttolerant control method with offline 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                   hybrid faulttolerant control is studied. Firstly, a closedloop fault model of the system with random delay parameters was established according to the Bernoulli 01 distribution; all possible prior faults are divided into a few intervals according to certain rules, and then an interval faulttolerant controller is designed offline according to the prior faults of each interval. Secondly, when the fault is estimated online, the corresponding interval faulttolerant 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.

Flight evaluation of a sliding mode online control allocation scheme for fault tolerant control Abstract   This paper develops a sliding mode fault tolerant control scheme based on a Linear Parameter Varying (LPV) system representation of the plant. The scheme includes a control allocation component, which is capable of utilizing the available healthy actuators in the face of actuator faultsfailures, in an effort to retain close to nominal fault free performance. The proposed scheme is validated using the Japan Aerospace Exploration Agencyxe2x80x99s MultiPurpose Aviation Laboratory (MuPAL   xcexb1   ) research aircraft. The flight test results demonstrate good lateraldirectional state tracking performance with no visible performance degradation in the presence of rudder and aileron faults.
