Industrial Automatic Control Systems and Controllers Annotation << Back Features of the DC Motor Control System with a Speed Observer V.I. Domanov, A.V. Domanov, Al’taxer Abbas A. Karim The operation of the DC motor speed stabilization system is considered. The feedback signal is generated by the speed monitor circuit. The work of the system is analyzed under the condition that the parameters of the element of the model in the composition of the observer differ from the parameters of the real element of the system. A transfer function of a closed system is obtained. The conditions of robust stability of the system are determined by a polynomial method. It is shown that for the normal operation of the stabilization system it is necessary to observe a number of conditions. For their implementation, it is advisable to shift the settings of the element of the model to increase. The results of the simulation of the system under study are presented. It is noted that when the adjustment of the model is shifted, the oscillation decreases. Keywords: observer; model; element parameters; robust stability; engine speed; polynomial method.
