Abstract

A new estimation algorithm is presented which provides exponential estimation of rotor resistance for induction motor drives in physical operating conditions. The exponential convergence is not influenced by the value assumed by rotor speed, including zero speed. The algorithm also provides flux estimates and may be viewed as an adaptive observer. Experimental results show good performance with a sampling time of 0.8 ms which makes the algorithm implementable on-line by available digital signal processors
