Research on Fuzzy Control in Networked Control System Based on Time-delay Identification

Aiming at the networked control problem, a united model is established including variable network time-delay and data dropout, etc. Based on the multi-rule such as error-threshold and maximum time-delay allowed, the network-scheduling algorithm is presented. Under the known model of the controlled object, the fuzzy controller is used as inter-model part of Smith control and the Smith pre-estimation part is integrated with the controlled object, which reduces the transformation of redundant information and compensates the network-induced delay. Simulation results show that the proposed methods are valid and effective.
