Abstract
Deals with stability properties of two known flux observers for induction machines. It is shown that an arbitrary fast convergence rate in one of the observers is achieved at the expense of its robustness against uncertainty in the rotor angular velocity. Another observer is proven to retain stability notwithstanding any error in the angular velocity measurements, but its estimation error convergence rate is limited by the rotor time constant
