Abstract

This paper discusses a method to determine the continuous-time parameters of induction machines which are necessary to implement the field-oriented control strategy. This method does not require the use of any mechanical devices or speed measurement and it is conceived to be used in the drive auto-commissioning phase. The estimation of the stator resistance is based on the DC machine model. The estimation of the stator transient inductance, the stator inductance, and the rotor time constant, is based on the dynamic machine model. Experimental results are presented and demonstrate the feasibility of the proposed approach
