摘要
研究了永磁同步电动机（ＰＭＳＭ）伺服系统的一种新型数字电流环方案，该方案采用了规则采样法生成ＰＷＭ波的比例型电流调节器，提出用前馈补偿和变电流环增益技术才能提高电流调节性能，给出了数字仿真和实验结果。
This paper presents a novel full-digital current strategy for a servo system with a perma-nent magnet synchronous motor,in which a proportional current regulator with regularlysampled PWM is used. Current feedforward compensation and variable proportional gaincontrol techniques are used to improve the performance of the current regulator. Digital sim-ulation and experimental results are given.
