A new on-line detection method of magnet fluz linkage for permanent magnet synchronous motor
According to the shortcoming that KF and EKF can only estimate the parameter of the PMSM in time domain, a new multi-scale default detection method is developed by combining KF and wavelet transform. By monitoring the voltages and currents of the stator, it is possible to estimate the permanent magnet flux linkage on-line, which has the advantage of KF and wavelet transform. The new filter not only possesses the multiscale analysis capability both in time domain and frequency domain, but also has better estimation accuracy than traditional KF. Computer simulation shows the effect of the new algorithm.
