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 two subprocesses, which are described by dynamical models with inertia (second order) with nonminimal phase. A tuning algorithm of linear controllers in internal and external contour are tuning in conformity with the maximal stability degree method. In the internal contour are used controllers P and PI, in the external contour are used controllers P, PI, PID. There are using the iterative procedure, for determinate of the optimal tuning parameters of controllers P, PI, PID. The tuning algorithm of controllers represents an algebraic method, which consists of two stages. The procedure is used to solve a particular example of tuning controllers P, PI, PID in multiple-loop feedback control systems.
