针对开关磁阻电机（SRM），提出了一种单相无位置传感器容错控制策略。该策略由相电感斜率过零检测方案和一系列相电感分区逻辑算法组成，能够在正常运行和单相缺相故障运行时捕获至少一相的对齐位置。利用在每个电周期中记录的索引位置，可以相应地估计用于无传感器驱动的转子位置。为了保证该方法计算相电感的稳定性，开关磁阻电机应在单脉冲控制模式下启动和运行。针对无位置传感器起动，提出了一种基于空载电感双阈值的无位置传感器综合起动方案。该控制策略易于实现，能保证无速度传感器系统在全速范围内稳定运行。此外，它不需要任何事先测量过程，复杂的逻辑算法，或复杂的数学计算。理论分析和实验结果验证了该控制策略的可行性。
A sensorless control strategy with one-phase lacking fault-tolerant capability is proposed in this paper for the switched reluctance motors (SRM). This strategy consists of a phase inductance slope zero-crossing detection scheme and a series of phase inductance partition logic algorithms, which is capable of capturing at least one-phase aligned position under both normal operation and one-phase lacking fault operation. With the recorded index position in each electric period, the rotor position can be estimated for sensorless driving accordingly. To ensure stable calculation of the phase inductance in this method, the SRM should be started and operated under single pulse control mode. Thus, for sensorless starting, an idle phase inductance double thresholds based sensorless synthetic starting scheme is also developed. The proposed strategy is easy for implementation and can ensure stable sensorless operation in full speed range. Moreover, it does not need any prior measuring process, complicated logic algorithm, or complex mathematical calculation. The theoretical analysis is conducted, and experimental results are provided to verify the feasibility of the proposed control strategy.
