Abstract

A new method for sensorless speed estimation of AC machines, using the analytic wavelet transform of the stator current signal, is proposed for a Direct Torque Control drive. A comparison with results obtained using the short time Fourier transform is included. The proposed method can be implemented in real time on a DSP. The time-frequency resolution obtained and the computation time required by the proposed algorithm are improved in comparison to existing techniques, and the method can be applied over the entire speed range.
