Research on Mixed Scheduling Algorithm in Networked Control System

The performance of Networked Control System(NCS) depends on the message scheduling.However,most scheduling algorithms make the time characteristic as the basis for establishing the priority,which can not show the importance of information.A mixed scheduling algorithm based on Maximum Error First(MEF) algorithm is proposed,in which the Maximum Change First(MCF) algorithm is major and the Larger Delay Lower Priority(LDLP) algorithm is minor.This new algorithm enriches the basis for establishing the priority.Simulation experimental results show this mixed scheduling algorithm can promote the whole performance of the control system effectively.
