Suppression of Common Mode Current for Permanent Magnet Synchronous Motor Based on Control of Model Prediction
摘要
Abstract
The common mode current in the drive system of permanent magnet synchronous motor (PMSM) is large,which is mainly affected by the control method.Firstly,prediction model of PMSM was established,and a simple model predictive direct torque control (MPDTC) method was proposed for PMSM based on performance evaluation function.And the implementation process of the prediction algorithm of simple MPDTC was described in detail.Secondly,The generation mechanism of system common mode current was analyzed,and the MPDTC based on the performance evaluation function was proposed to suppress the common mode current.Finally,simulation experiments of the proposed MPDTC were carried out and the comparison of MPDTC and DTC were conducted.The results showed that the proposed MPDPC was able to suppress common mode current.关键词
