Compensation for Packet Dropout in Networked Control Systems Based on Grey Generalized Predictive Control

For the problem of packet dropout in network transmissions,a new framework for networked control systems based on grey generalized predictive control(GGPC) is proposed.The networked control system is regarded as a grey system.A distributed model is designed,of which the controller node is driven by event-clock,and the sensor node and actuator node are driven by clock.Based on GGPC's characteristics of small amount of on-line calculation and combined with queuing strategy,a compensation scheme is proposed.The simulation result shows that the effects of the compensation scheme are good.
