Active Flux based control of ALA Rotor SynRel with MTPA, Maximum Power Factor and Maximum Torque per Flux

High Energy conversion control of ac motor drives with seamless swapping from maximum torque per ampere (MTPA) to maximum power factor (MaxCosPhi) and then to maximum torque per flux (MTPF) to cover all the torque-speed envelope points, based on the “active flux“ concept with a case study for ALA-SynRel machine with experiments constitutes the contribution of the present paper.
