Vector control of maglev PMLSM based on minimum loss SVPWM method

According to the special structure and operation mechanism of the maglev permanent magnet linear synchronous motor (PMLSM), this paper established a theoretical mathematical model of electromagnetic thrust and levitation force of the motor in two-phase rotating reference frame and then realized the stability control of PMLSM with the simulation models under vector control (VC). Considering the large loss of inverter switches, this paper finally established minimum switching loss model of the inverter. Simulation results verify the feasibility and validity of the methods referred before.
