一种增强低载波比运行的单采样双更新调制方法

To solve problems of low-accuracy synthetic voltage vector, large current ripple, and poor stability in sensor/sensorless control of permanent-magnet synchronous motors (PMSMs) under low-carrier ratio operations, a single sampling double update space vector pulsewidth modulation (SSDU-SVPWM) is proposed. In this method, the phase current is sampled only once, however the target voltage vector is c...
