Titel:
Demodulation approach for slowly sampled sensorless field-oriented control systems enabling multiple-frequency injections. 
Abstract:
This paper describes a demodulation approach based on the least squares method for a saliency based position estimation in slowly sampled field-oriented control systems. The proposed approach focuses on the sensorless control of electrical drives in which the sample rate of the control task is chosen slower than both the maximum possible update rate of the phase voltages and the maximum possible sample rate of the phase current measurement by a multiple. Under those conditions it is possible to...    »
