Hybrid Active-Passive α-stability Fault-Tolerant Control Research of Nonlinear NCS under DETCS

Aimed at the nominal nonlinear NCS, the design of hybrid active-passive α - stability fault-tolerant controller under DETCS is investigated. Considering the event-triggered condition, network induced delay and actuator fault with failure, a nonlinear NCS model is established. And passive α - stability fault-tolerant controller was designed to ensure the system α - stability when a fault in the set occurred and slow down the rate of performance deterioration when a fault out the set happened. The fault information is detected by fault detection observer. Once the accurate fault information is obtained, the active compensation is taken immediately. The correctness and effectiveness of the results are verified by a simulation example.
