快速可靠的匝间短路检测对于机器驱动系统至关重要。 PMAC机器总是与控制器一起工作，控制器参数会影响机器的性能和故障诊断。电流控制器带宽的影响特别令人感兴趣。在闭环控制 PMSM 驱动系统中，从理论上研究了由匝间短路引起的电流和电压中的二次谐波的行为以及带宽。为了结合电流和电压中的故障信息，提出了一种基于瑞利商的指标，并与已发表的指标（瞬时无功功率的二次谐波）进行了比较。通过联合仿真验证，所提出的指标在控制器带宽方面更加稳健。
Fast and reliable inter-turn short-circuit detection is essential for machine drive system. PMAC machines always work together with controllers and the controller parameters will affect the machine performance and the fault diagnosis in turn. The effects from the current controller bandwidth are special interested. In a closed-loop control PMSM drive system, the behaviours of the second harmonics in currents and voltages, induced by inter-turn short-circuit, along with the bandwidth are investigated theoretically. To combine the fault information both in currents and voltages, an indicator based on Rayleigh quotient, is proposed and compared with one published indicators, the second harmonics in instantaneous reactive power. Validated by Co-simulation, the presented indicator is more robust with respect to the controller bandwidth.
