A Low Complexity Two Step Predictive Torque and Flux Control Scheme for PMSM Drive

Simple predictive torque control of an open‐end winding interior permanent magnet synchronous motor drive without weighting factor for electric vehicle applications

“…Tuning of the WF or selection of the WF will deteriorate the performance of the machine. Some of the WF elimination techniques are presented in previous studies 22–27 . The two weighting factorless PTCs are introduced in Zerdalı et al, 22 which reduce the torque ripple and improve the performance of the machine, but the switching frequency is getting affected.…”

“…A WF of stator flux in Zhang and Yang 25 is eliminated by converting the torque and flux magnitude references into an equivalent reference vector of stator flux which reduces the ripples, but the dynamic condition operation is affected. By converting the flux component into a reactive torque component and using it in CF optimization, WF can be eliminated in PTC‐based PMSM, 26 with reduced VV strategy to reduce the computational burden on the processor. Using ranking analysis, the top 20 VVs that provide the lowest value for the FCF are utilized to evaluate the TCF; then, an optimal VV is selected which gives least error in FCF, thereby eliminating the WF 27 which provides certain computational burden on the processor.…”

“…Some of the WF elimination techniques are presented in previous studies. [22][23][24][25][26][27] The two weighting factorless PTCs are introduced in Zerdalı et al, 22 which reduce the torque ripple and improve the performance of the machine, but the switching frequency is getting affected. By eliminating the WF, the induction motor is driven with predictive flux control using a three-level neutral-point clamped inverter, but the requirement of the number of switches is increased.…”
