Regenerating-mode stabilization of the "statically compensated voltage model''
Artikel i vetenskaplig tidskrift, 2007

Reversal of rotation under load of sensorless induction motor drives is very challenging, as there is often an unstable region in the low-speed regenerating mode. In this paper, a variant of the classical "voltage model," i.e., the "statically compensated voltage model," is modified for stable regenerating-mode operation with accurate model motor parameters. The mechanisms behind two low-speed instability phenomena are thereafter, explored, and methods for avoiding instability with inaccurate model parameters are developed. Experimental results verify the theory and show adequate performance.
