Active Flux Based Control of ALA Rotor SynRel with MTPA, Maximum Power Factor and Maximum Torque per Flux Considering Magnetic Saturation

High Energy conversion control of ac motor drives that considers magnetic saturation and computes, based on the Newton-Raphson method, the “active flux” trajectories for maximum torque per ampere (MTPA), maximum power factor (MaxCosPhi) and maximum torque per flux (MTPF) to cover all the torque-speed envelope points, based on the “active flux” concept is presented in this paper. A case study for ALA-RSM with digital simulations and preliminary experimental results constitutes the contribution of the present paper.
