Parameters identification and their errors for AC motor drive systems using the single current sensor technique

An estimation scheme is used for solving two practical problems of the single current sensor technique. To improve the effect of parameter uncertainties the method that identifies motor parameters for AC motor drive systems using the single current sensor technique is presented. And the parameter identification error and its cause atre examined. It gives good performances for identify in parameters and reconstructing phase currents.
