摘要
分析了电机无传感器测速方法,给出了采用STFT解决这一问题的具体方法,并与采用小波分析的方法进行了实验比较。从实验结果看,STFT计算时间短,精度高。
The sensorless speed detection during the motor testing is analysed. The method to solve this problem based on STFT is worked out. The comparison between the two methods using STFT and wavelet is also given out. The comparison shows that the method using STFT is better than that using wavelet both in calculation time and precision.
