| Abstract |
Difficulties in the stability analysis and design of several back EMF based speedsensorless
induction motor drives arise for lack of an explicit MRAS structure. To overcome this
problem, an equivalent MRAS representation of the speed estimator is given, using which stability
conditions are analytically derived. A new design strategy is then proposed to guarantee the stability
for the whole operation including the regenerating mode in the low speed region. Validity of the
theoretical results is verified by simulation and experiment. |
