摘要
连续极永磁(consequent-pole permanent magnet,CPPM)电机是一种特殊结构的混合励磁同步电机。该文根据电压、电流约束条件,推导了全速度范围内的CPPM电机理论最大转矩输出的必要条件。在此基础上,考虑CPPM电机的结构特点和电机参数变化特性,研究了一种实现CPPM电机宽速度范围最大转矩输出的弱磁控制方法。CPPM样机的实验结果表明,所提出的弱磁控制算法具有较强的参数鲁棒性,可以实现电机宽速度范围高响应控制性能。
The consequent-pole permanent magnet（CPPM） machine is a special-structured hybrid excitation synchronous machine（HESM）.Its necessary conditions of the theoretical maximum torque output are derived in this paper considering voltage and current constraints over the whole speed range.Furthermore,based on the special structure and parameter characteristics of the CPPM machine,a flux weakening control algorithm for CPPM machine is designed for maximum torque output within a wide speed range.Experiment results of a CPPM machine prototype show that the presented algorithm is robust to parameter variations and can achieve high response in the entire flux weakening speed region.
