Abstract
An approach is proposed to automatic control of the speed of traction unit with synchronous motors on permanent magnets containing starter windings, which is based on the use of reduced–order observers. An equation of Luenberger's observer for estimating non–direct measurable variables is obtained and structural schemes of Luenberger's observer for estimating currents in starter windings of an engine are developed. The structural scheme of the automatic control system of the traction unit speed and its computer simulation model is developed. The study of the effect from application of the developed automatic control system have shown that the use of this system allows to achieve a reduction of iq current pulses, electric power losses and a decrease in the pulsations of the moment on a shaft of synchronous motors of the with permanent magnets.
