CONTROL OBJECT IDENTIFICATION USING CLOSED-LOOP SYSTEM TRANSIENT RESPONSE

Abstract

The method of control object identification using the transient response of closed-loop system is given. The transient functions of typical elements are considered. These elements are the inertial element of first, second and higher order and the oscillating element. Analytical expressions allowing to determine parameters of control objects transfer functions using parameters of transient functions of the closed-loop systems are received. The parameters of various control objects are calculated on a concrete example. The digital regulators are synthesized using the discrete transfer functions of control objects. The digital modeling is realized for calculations verification. Recommendations concerning practical application of the received results are presented.
