Abstract:

The causes of de-saturation overshoot of the speed regulator are analyzed.The speed and current are linearized for the preliminary work of the overshoot of the de-saturation.This paper also derives the theoretical basis for translating the overshoot by the typical type II system immunity indicators.It finally comes to several conclusions of practical value and can,therefore,be used as a guide in practice.

Key words: electric drive;DC converter;multi-loop control;regulator;de-saturation overshoot
