Tuning Controllers in the Multiple-Loop Feedback Control System to the Objects with Inertia, Time Delay and Non Minimal Phase

Abstract

This paper proposes a tuning algorithm of linear controllers P, PI, PID in the multiple-loop feedback control systems. The control object consists of two subprocesses, which are described by the dynamical models with inertia (first and second order), time delay and non minimal phase. The controllers in the internal contour and in the external contour tuning use the maximal stability degree method. P and PI controllers are used in the internal contour and P, PI, PID controllers are used in the external contour.
