Control Strategies for Network Systems Based on a Novel Event-Trigger Mechanism

In this paper, a kind of data retransmission mechanism for network control system based on event trigger is introduced, to reduce the influence caused by packet loss in the process of network communication. At first, this paper presents an event trigger mechanism, to be applied to judge whether the signal of the sensor to be sent to the controller through the network, the network control system model combining with the data retransmission mechanism is constructed, then analyzing the stability of this system and constructing feedback gain for this model accordingly. Finally through the simulation experiment proves the effectiveness of the method.
