摘要: This paper presents the control method for mono inverter dual parallel (MIDP) surface-mounted permanent-magnet synchronous motor (SPMSM) drive system. Unlike MIDP induction machine system, SPMSM system suffers from inherent instability due to lack of slip. The proposed active damping refrains oscillation coming mechanical and electrical unbalances enables stable operation. also simple maximum torque per ampere Mathematically calculated optimal currents reduce amplitude improve efficiency. To maximize merits a sensorless algorithm is applied. Experiments with 600-W SPMSMs are executed verify feasibility method.
