Abstract :
This paper attempts to resolve a major area of concern for self-commissioning of induction machine drives: easily implemented methods capable of accurate parameter estimation. Most of the self-commissioning techniques are based on some form of statistical analysis. Classical statistical techniques such as ARMA (z-transform) methods using sampled line voltages, phase currents, and rotor velocity can easily produce large (2× or more) parameter errors. The first principles causing the errors and the methods of reducing those effects to tolerable levels is the focus of this paper
