Acordarea Regulatoarelor în Sisteme de Reglare în Cascadă cu Trei Contururi cu Inerţie

Abstract

A tuning algorithm of linear controllers P, PI, PID in multiple-loop feedback control systems is proposed in this paper. The control objects consist of three subprocesses, which are described by dynamical models with inertia (fourth order). The controllers in the internal contours first and second and in the external contour are tuning according the maximal stability degree method. In the internal contour first and second are used controllers P and PI, in the external contour is used controllers P, PI, PID. The maximal stability degree method represents the iterative procedure, for determinate the optimal parameters of controllers P, PI, PID in the multiple-loop feedback control systems.
