Title
Operation-Area-Selected Overmodulation Strategy for Flux-Weakening Control of Surface-Mounted Permanent Magnet Synchronous Motor
Abstract
In the traditional overmodulation, the reference of voltage loop is selected as a constant. However, it keeps the motor working in the six-step mode regardless of torque demand, resulting in current and speed harmonics.To address this problem, an operation-area-selected (OAS) overmodulation strategy is proposed for flux-weakening control of surface-mounted permanent magnet synchronous motor. The compensation of the inscribed circle reference voltage is obtained by logical judgments of two designed reference voltages in an auxiliary closed-loop. The proposed scheme can adjust the reference of voltage loop dynamically according to different working conditions, leading to reduced current and speed ripples. The simulation results verify the effectiveness of the studied scheme.
