| Abstract |
Reduced-order observers for rotor flux estimation of induction machines are considered. Only observers that do not u!se the rotor speed in their equations are studied (inherently sensorless schemes). An observer, which significantly improves the damping of the traditional "voltage model", is presented. It is shown that the flux dynamics form a nonlinear closed-loop system when the flux estimate is used for field orientation, and instability at low speeds is indicated. |
