An Event-triggered Control System to Detect Network Disconnection

Abstract

This paper presents a new event-triggered control system to detect anomalies in communication links. With state feedback, the event-triggered control system is constructed for an augmented system consisting of the plant and an integrator with an auxiliary signal. If network disconnection occurs, then the output of the integrator exceeds a threshold due to the effect of the auxiliary signal. Monitoring this behavior can detect disconnection. Furthermore, the maximum detection time can be arbitrarily specified by the magnitude of the auxiliary signal.
