Energy Efficient Open Loop Control of Permanent Magnet Synchronous Motors for Fan Applications

The paper deals with the problem of V/f control of a Permanent Magnet Synchronous Motor without winding dumper for fan applications. Based on stability analysis, an additional stabilizing loop is introduced. Voltage optimization was carried out in order to minimize the input power of PMSM. Simulation results confirmed the validity of the applied solution for fan applications本文针对风机应用场景下无绕组泄放回路的永磁同步电机（Permanent Magnet Synchronous Motor，PMSM）的V/f控制问题展开研究。基于稳定性分析，本文引入了附加稳定回路；为最小化该永磁同步电机的输入功率，开展了电压优化工作。仿真结果验证了所提方案针对风机应用场景的有效性。
