Abstract

Digitally controlled permanent-magnet synchronous motors (PMSMs) exhibit bandwidth limitations imposed by delay. In high power applications such as rail transit, the negative impact of delay is particularly serious due to the low switching frequency of the inverter. In this paper, the causes and effects of time delay are analyzed, and the sampling delay is greatly reduced by using multiple sampling method. Test results are given to verify the effectiveness and reliability of the proposed method.
