Cb. Jacobina et al., On-line estimation of the stator resistance of induction machines based onzero-sequence model, IEEE POW E, 15(2), 2000, pp. 346-353
This paper proposes a technique to estimate. the staler resistance of induc
tion machines. The stator resistance is obtained by solving a least squares
minimization problem, which solution also provides the value of the leakag
e inductance. The technique exploits the machine behavior with respect to z
ero-sequence quantities, It is conceived to be used on-line with the drive
strategy without disturbing the angular shaft speed. Experimental results a
re used to demonstrate the feasibility of the proposed technique.
