摘要： A system and method for controlling an interior permanent magnet synchronous motor (IPMSM) are presented. In an exemplary implementation, phase current ripple estimation techniques are utilized for variable frequency switching pulse-width modulation control of the IPMSM. In one implementation, the method includes controlling a three-phase inverter based on an initial switching frequency to generate a three-phase alternating current (AC) voltage for the IPMSM. Transformed voltages are determined in a rotating reference frame based on the three-phase AC voltage in the stationary reference frame. Current ripples are determined in the rotating reference frame based on the transformed voltages. Phase current ripples are determined in the stationary reference frame based on the current ripples in the rotating reference frame. A modified switching frequency for the three-phase inverter is determined based on the initial switching frequency and the phase current ripples. The three-phase inverter is then controlled based on the modified switching frequency.

摘要： Techniques are presented for more efficient three-phase inverter control for electrified vehicles (EVs). The techniques can be executed by a controller of an EV that includes one or more processors. Specifically, the techniques include closed-loop discontinuous pulse-width modulation (DPWM) control of a three-phase inverter based on electric motor current feedback. The three-phase inverter control techniques can be further based on electric motor/rotor position feedback. Based on the feedback, the techniques can select one of a plurality of zero-voltage vectors in real-time. The selected zero-voltage vector can be used when generating duty cycles for switching of the three-phase inverter, which can result in decreased switching losses and increased efficiency of the three-phase inverter.
