Implementation of modified smith predictors into a matlab program

Abstract

The main aim of the paper is to present a Matlab program for control of time-delay systems using three various modifications of Smith predictor. The software implementation includes the modification for unstable and integrating processes, PI-PD modification for systems with long dead time, and modification applying control design by Coefficient Diagram Method (CDM). The freely downloadable program offers appropriate computational and simulation capabilities accompanied by a simple Graphical User Interface (GUI). Its application potential is illustrated on two control examples. © ECMS.
