摘要:
This paper proposes a current injection based simultaneous stator winding and permanent magnet (PM) temperature tracking technique for dual three-phase permanent magnet synchronous machines (PMSMs). The estimation models involving winding and PM temperature are derived for different control strategies with inductance cancellation and free voltage source inverter (VSI) nonlinearity effect. To improve the tracking performance, the Kalman filter is employed for simultaneous winding and PM temperature estimation. Compared with the existing method, the proposed simultaneous winding and PM temperature tracking strategy is independent of various operating condition which features free look-up table assistance. A laboratory dual three-phase interior permanent magnet (IPM) motor validate the proposed method under different speed and torque conditions.
