Online Permanent Magnet Temperature Estimation in Permanent Magnet Machines Using Nonlinear Observer With Enhanced Parameter Estimation to Minimise Risk of Demagnetisation

open access: yesIET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
Real‐time temperature estimation is critical in the control of traction drives for electric vehicles. Efficient control of conventional and novel PMSM machines requires awareness of permanent magnet (PM) temperature to avoid demagnetisation of the magnetic material.

An Electromechanical Coupling Resonance Suppression Method for IPMSM Drive System Considering the Fluctuation of DC‐Link Voltage

open access: yesIET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
With the consideration of the DC‐link voltage fluctuation, the motor output torque contains a large number of fluctuating components, which may trigger electromechanical coupling resonance (EMCR) and deteriorate the system control performance. In order to solve this problem, the model of the electromechanical coupled system is established, and the ...

Rotor Position Detection Method for Permanent Magnet Synchronous Motors Based on Search Coil Mutual Inductance

open access: yesIET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
This paper addresses the problem of traditional search coils being unable to detect the rotor position of permanent magnet synchronous motors (PMSMs) in low‐speed regions. A rotor position detection method based on the mutual inductance effect of search coils is proposed.

Efficient and Weighting Factor‐Free Predictive Current Control for Three‐Level PMSM Drives via Cost Function Division

open access: yesIET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
This paper proposes an enhanced deadbeat model predictive current control (DB‐MPCC) strategy for a 3L‐NPC inverter‐fed PMSM drive. The method integrates RVV‐based control set reduction, cost function division for weighting factor elimination and optimal duty cycle with switching frequency reduction, thereby minimising computational burden, tuning ...
