5. Real-Time Rotor Temperature Estimation Method for Interior Permanent Magnet Synchronous Machines : A method using a Lumped Parameter Thermal Network in combination with an estimation algorithm: implementation and comparison of a Dual Kalman Filter and a Dual Observer
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Accurate knowledge of the temperature of a Permanent Magnet Synchronous Machine is of high importance, not only to ensure safe operation and improve control of the operating point, but also to avoid irreversible demagnetization of rare-earth permanent magnets. However, direct measurement using thermal sensors is not suitable for high volume and low-cost applications, due to costly sensor installation and maintenance, and therefore, the magnet temperature needs instead to be estimated.
