摘要

随着永磁同步电机在节能减排中的广泛应用，永磁同步电机的开环控制策略也在动态性能要求不高的系统中得到广泛应用。开环控制系统的电压幅值在各个速度段的选取是决定开环控制性能的关键因素。在分析永磁同步电机开环控制基本原理的基础上，研究不同频率下不同电压幅值对系统性能的影响，在此基础上分析开环控制过程中电流输出特性。通过试验有效验证了理论分析的正确性。

Abstract

With more and more application of permanent magnet synchronous motor in energy conservation and emission reduction field, open-loop control strategies were used widely for no-high dynamic requirement. The voltage amplitude in each speed range was the key factor of the open-loop control system. Based on the principles of the open-loop control system, performances of different voltage amplitude under different frequency were studied; furthermore, analysis of the current-output characteristic were provided. Experiment results indicates the effects of the theory.
