On the Solution of the Setting Quality Problem for the Relay Controllers

Abstract

The paper considers a problem of setting the automatic control systems (ACS) including twoposition and three-position PID-controllers. The problem can be generally solved by a method of direct simulation analysis of transient response in ACS. To perform a parametric identification of the models of controlled objects, the numerical procedures of determining the optimal parameters of their differential equations have been developed for both experimental transient response curves and transient functions of the working closed systems. The algorithms of digital implementation for the relay controllers are presented. The results of process simulation in two-position and threeposition systems are analyzed. The outcomes of the research can be used to select the relay controller settings.
