“…Focusing on voltage equation at first, the comparison between (28) and (15) highlights no detectable differences; these are revealed by comparing (30) to (18), namely ξ φτ presents just the imaginary component compared to ξ ft , while the dependence of e φτ on ϑ pu is lightened by the square root operator compared to e ft . Both these considerations suggest that the φτ synchronous reference frame may be more suitable than the ft synchronous reference frame in terms of voltage saturation management and, thus, flux-weakening capability.…”

“…by carrying out current commutation in advance [17,18] or by varying DC-link voltage suitably [19,20]. The application of direct torque control has been also investigated [21,22], together with various vector control systems [23][24][25][26][27][28][29][30]. Most of these research efforts have been focused on suppressing or reducing PMBDCM torque ripple due to current commutation, but enhancing PMBDCM flux-weakening capability has been sometimes also consider [16-18, 23, 29].…”

The design of space vector control (SVC) systems suitable for flux-weakening operation of permanent magnet brushless DC machines (PMBDCMs) is presented in this study. The proposed design approach enables overcoming the critical issues arising from the non-linearities of PMBDCM voltage and torque equations; these issues derive from the trapezoidal shapes of back-emfs and affect PMBDCM constraint management significantly. The SVCs presented in this study have been developed within two different synchronous reference frames, both of which enable distinguishing torque and demagnetising current components clearly. Therefore, reference torque current component is determined in accordance with PMBDCM torque demand, while reference demagnetising current component is computed through a voltage follower PI regulator, which processes the voltage deficit detected on the DC-link. In this regard, a novel synchronous reference frame is proposed in this study, which improves PMBDCM constraint management and results into a wider constant-power speed range, but at the cost of some torque ripple. The enhanced performances achievable by SVC approaches are highlighted by numerical simulations, which regard the comparison among the SVCs and an SVC with no flux-weakening capability, at different operating conditions.

This article concentrates on the parameter estimation of brushless DC motor, where the stator current and winding back electromotive force are taken as the motor states, while the stator resistance and inductance are taken into consideration and augmented into the state vector. Based on this augmented model, a modified adaptive extended Kalman filter is proposed which updates the process noise covariance matrix in real time with the current input‐output data, and takes the state estimates by the traditional extended Kalman filter as one‐step estimation for the calculation of the covariance matrix. The convergence analysis is given to verify the theoretical results. Finally, the simulation results show that the proposed algorithm can effectively improve the estimation accuracy.

“…However, only torque ripple caused by current harmonics is considered in the paper, while parameter distortions and cogging torque are not considered. In reference [25], for the brushless DC motor, the torque ripple suppression current is calculated by establishing a coefficient of electromechanical energy conversion voltage and a special coordinate transformation. However, in this paper, only the harmonics in the no‐load back‐EMF are considered and the inductance harmonics and cogging torque are not considered.…”

Permanent magnet synchronous motors are widely used in electric vehicles. The permanent magnet synchronous motor torque ripple suppression is a research hotspot at present. This study adopts the torque ripple equation based on magnetic co‐energy. Two novel minimum current harmonics torque ripple suppression strategies based on the magnetic co‐energy are proposed. Both methods are suitable for whole current map calculation. One is based on dq‐axis model, which makes the dq‐axis current harmonics fluctuate along gradient direction of the torque equation to dq‐axis currents. The other one is based on the newly proposed torque–current coupling model. The minimum current harmonics obtained by the two methods are basically the same. At last, finite element method and test bench experiment are used to verify the two methods. Both of them can effectively suppress torque ripple.
