| 摘 要： | 针对永磁电机抗干扰能力较差、波形输出转换控制能力较弱的问题，提出带有不匹配干扰的永磁电机电磁波形优化控制方法。根据永磁电机电磁波形采样节点分布聚类条件构建永磁电机电磁波的信号模型，采用匹配滤波检测器完成永磁电机电磁波形输出抗干扰抑制，提取永磁电机电磁波形信号的统计特征量，结合关联特征谱分析方法进行永磁电机电磁波信号的耦合处理，建立永磁电机电磁波信号的模糊特征匹配模型，对永磁电机电磁波形进行聚焦处理，根据特征聚集结果求得优化控制参量，完成永磁电机电磁波形的输出转换控制和匹配干扰抑制。仿真结果表明，采用该方法进行永磁电机电磁波形控制的抗干扰性较好、对电磁波形的输出转换控制能力较好，波形检测性能较强。

| Abstract: | Aiming at the problems of poor antiinterference ability of the permanent magnet motor and weak control of waveform output conversion,an electromagnetic wave optimization control method for the permanent magnet motor with mismatch interference was proposed.The electromagnetic wave signal model of the permanent magnet motor was constructed based on the distribution and clustering conditions of the electromagnetic waveform sampling nodes of the permanent magnet motor.The matched filter detector was used to complete the antiinterference suppression of the electromagnetic waveform output of the permanent magnet motor.The correlation feature spectrum analysis method performs the coupling processing of the electromagnetic wave signals of the permanent magnet motor,establishes a fuzzy feature matching model of the electromagnetic wave signals of the permanent magnet motor,focuses the processing on the electromagnetic waveform of the permanent magnet motor,and obtains the optimal control parameters based on the result of feature aggregation to complete the permanent magnet output conversion control of motor electromagnetic waveform and matching interference suppression.The simulation results show that the electromagnetic wave control of the permanent magnet motor using this method has better antiinterference performance,better control of electromagnetic wave output conversion,and stronger waveform detection performance. |
