摘要：
A new reduced-order algorithm to be used to estimate the rotor flux components of induction motors with schemes such as field-oriented control is described in this paper. The algorithm is based on the extended Kalman filter theory and estimates the desired quantities on line by using only measurements of the stator voltages and currents, and rotor speed. The on-line adaptation of the inverse rotor time constant makes it possible to obtain very accurate estimates of rotor flux components, in spite of temperature and magnetic saturation effects. The algorithm order reduction decreases the computational complexity and makes the proposed estimator superior to the other ones based on the EKF theory.
