摘要
研究了一种双CPU全数字控制转子加额外磁阻铁心的新型表面式永磁同步电动机的弱磁控制系统,对系统中弱磁算法、转速计算和速度调节器作了深入探讨,得到了较好的实验结果.
This paper describes a full-digital control system in the flux-weakening mode with two microprocessors for a new surface-mounted permanent magnet synchronous motor, which has an additional reluctance rotor part. The reluctance part has a very high d-axis but low q-axis reactance. For flux-weakening, the d-axis armature current is adequately controlled with one of the microprocessors. The novel current control scheme and velocity regulator are presented. Experimental results show that the speed range of the new motor is expanded.
