摘要
提出了一种新型的无刷直流电机无传感器控制系统的位置检测方法———基于FIPS的反电动势3次谐波检测法,该方法采用FIPS(frequency-independent phase shifter)独立频率相移器,在整个调速范围内均能得到准确的转子位置信号。仿真结果证明了该方案能很好地改善系统的低速性能,拓宽系统调速范围。
A novel detecting method of rotor position of BLDC based on the third harmonic components is presented. By using FIPS（frequency-independent phase shifter）, the accurate position of rotor can be calculated within a wide speed range in the proposed sensorless control scheme. The performance is proved well by the simulation result, speed range is widened.
