Event-triggered anti-disturbance fault tolerant control for switched networked control systems

This work centres on the event-triggered anti-disturbance fault-tolerant (ETADFT) control problem for unknown switched networked control systems (USNCSs) with dual-source disturbances and unknown faults by the multiple Lyapunov functions method. A dynamic memory event-triggered (DMET) mechanism is developed to optimise the utilisation of transmission resources. A composite switching observer is devised to approximate the unmeasurable state, fault and disturbance. By utilising the DMET mechanism, composite switching observer and time-relevant switching regulator, an ETADFT controller is formulated to counteract the impact of the unknown disturbance and tolerant unknown faults. Finally, the suggested ETADFT control strategy is implemented on the switched RLC circuit model to verify the rationality of the control mechanism.
