Thyristor electric drive with optimal control

Abstract

The questions of construction and technical realization of electric drives according to the integral quadratic estimation of electric drives according to the integral quadratic estimation of electric drives on the system G-D with a thyristor activator and B-D with a relay control system are considered. Recommended for these electric drives is a reversible thyristor DC converter (RTP). The frequency of the alternating regime in the system GD with RTP is 90-100 Hz, and in the system B-D reaches 600 Hz. Increasing the frequency positively affects the quality of the transient process and can be achieved using as a relay regulators of operational amplifiers YAFK-0301, magnetic operational amplifiers with a frequency of 10 kHz winding or integral operational amplifiers of the K1UT-401 type, as well as the replacement of thyristors of the series T thyristors of the PM series.
