Metaheuristic Algorithm–Based Parameter Estimation for Permanent Magnet DC Motors

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
This study proposes a robust parameter estimation strategy for identifying seven critical permanent magnet DC motor parameters by minimizing the root mean square error (RMSE) between measured and estimated speed profiles. A comparative analysis evaluates the performance of original particle swarm optimization (PSO), a modified PSO utilizing a ...

Online Parameter Identification of SPMSMs Under Sensorless Control Cancelling Influence of Position Error With Torque Measurements

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
Firstly, it is revealed that stator inductance and PM flux linkage can be independently identified, which can eliminate the influence of unknown inverter nonlinearity and stator resistance by only combining dq‐axis voltage equations. Then, with the help of torque measurement, the correlations of stator inductance, resistance and PM flux linkage with ...

Estimation of Electric Power Quantities for Nonsinusoidal Conditions Based on Operating Point Fluctuations

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper proposes an operating point fluctuations (OPF) framework to describe nonsinusoidal, nonstationary waveforms by modeling distortions as amplitude and phase fluctuations of a time‐varying fundamental component. Based on OPF, single‐phase and three‐phase power quantity expressions consistent with IEEE Std. 1459–2025 are derived under stationary

Parameter Estimation of PMSM Based on Improved Secretary Bird Optimization Algorithm

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
Figure 5 illustrates the vector control system. The ISBOA takes the motor signals id,iq,ud,uq,andωr${i_d},{i_q},{u_d},{u_q}, \text{ and }{\omega _r}$ as inputs, and estimates the key parameters: stator inductance Ls,${L_s}, $ stator resistance Rs,${R_s}, $ and permanent magnet flux linkage ψf$\psi_f$.
