Tóm tắt

This paper proposes a technique to determine the on-line stator resistance of a four-phase induction machine in a four-phase drive system. Besides the stator resistance, the stator leakage inductance can also be estimated. These parameters are obtained by solving a least squares minimization problem. The technique is conceived to be used on-line with the drive strategy without disturbing the machine electromagnetic torque. Experimental results are used to demonstrate the feasibility of the proposed technique.
