Study on Networked Control for Power Electronic Systems

This paper proposes a novel control strategy based on network for power electronics system. The definition of networked control is presented in control through network and control of network. According to the actual situation of power electronics, network selection and communication mechanism are presented. By means of the communication cell, standardized data stream of control loop and characteristics of network- induced delay through communication, some concepts of control through network is described. After the rough estimation of network-induced delay of all kinds of network during the transmission process for data of power electronics, the strategies of networked control for power electronic systems are presented by different MAC and topologies, which embody the essence of control of network.
