Compensation of Acting Load Influence on Static Characteristics of Electric Drive by using Inertia Moment Observer

V. Geleževičius

Abstract


The possibility of acting load influence on static characteristics of DC drive compensation by using inertia moment observer is investigated. It is demonstrated that in dynamic state of the drive observer identifies inertia moment of the moving part and gives a signal for speed controller gain correction for quantitative optimum condition ensuring. In the steady state of the drive the observer serves as speed error provoked by acting load minimisation by means of speed controller gain increasing. Modeling results of the system are presented. Ill. 6, bibl.4 (in English; summaries in English, Russian and Lithuanian).
