针对开关磁阻电机无位置传感器下的转子位置还原,提出一种基于电流上升时间监测的无位置传感器控制策略,该策略包含初始位置检测、电机启动运行、转子位置重构和调速控制几个部分。首先离线测得电机在特殊位置时滞环带宽内的电流上升时间,作为初始阈值用于电机启动;接着分别对各相绕组注入小电流,比较各相电流在滞环带宽内的上升时间进行初始位置分区;然后将转子从电感下降区进入电感最小区起始点作为特征点,利用初始阈值启动电机并在电机运行过程中依据实时工况更新特征点处时间阈值作为下一周期的检测特征;最后通过检测特征点位置信号对转子进行位置重构和转速估算实现换相与调速。仿真与实验结果验证了所提出控制策略的有效性与准确性。
