Distributed controller design for controlling a system with plant uncertainties over network

Abstract

Distributed controller design for a Networked Control System (NCS) with plant uncertainties is proposed in this paper. Communication delays in the NCS are compensated with the designed robust controller using the graphical loopshaping technique. For plant uncertainties, a robust control loop is then designed based on the RNMFC scheme and augmented to the existing control system. The experimental result illustrates the benefits of the proposed method with the speed control of a dc motor over network. © 2005 SICE.
