Optimization of the microprocessor current controller of the thyristor electric drive for the required control speed.

Abstract

The issues of microprocessor control of the thyristor drive current are considered. It is shown that in the continuous current mode, aperiodic regulation with the required (including maximum) speed can be obtained with a constant control algorithm due to the appropriate selection of the algorithm parameters. In a discontinuous current mode, the desired dynamic characteristics of the regulation can be provided by non-linear correction.
