    • Disclosed is a method and apparatus for detecting an excitation position of an SRM by comparison of detected currents. The method includes detecting a current by applying a first test voltage to each phase of the SRM, detecting a current by applying a second test voltage to each phase, determining an operation state of the SRM based on a deviation between the currents detected in any one of the phases, determining the operation state of the SRM as a rotation state if the deviation value exceeds a predetermined value, and applying a third test voltage to a phase excited just prior to a current excited phase to detect the current and turning on a phase to be next excited if the detected current value is more than a first reference value, and turning off the phase excited just prior to the presently excited phase if the detected current value is more than a second reference value. The phase excitation position is accurately detected according to the rotating speed without using a position sensor.
    • 公开了一种通过比较检测电流来检测SRM的激励位置的方法和装置。 该方法包括通过对SRM的每个相位施加第一测试电压来检测电流,通过对每个相位施加第二测试电压来检测电流,基于在任何一个中检测到的电流之间的偏差来确定SRM的操作状态 如果所述偏差值超过预定值,则将所述SRM的运行状态确定为旋转状态,以及将第三测试电压施加到刚好在当前激励相位之前激发的相位,以检测所述电流并打开相位 如果检测到的电流值大于第一参考值,则接下来激发,并且如果检测到的电流值大于第二参考值,则关闭刚好在当前激励阶段之前激发的相位。 在不使用位置传感器的情况下,根据转速精确地检测相位激励位置。

    • Disclosed is a method for suppressing a speed ripple occurring during an operation of an AC motor by using a torque compensator based on an activation function. The method includes the steps of calculating a speed error ωerr based on a reference speed ωref and an actual speed ωact; calculating a controller output Trm by using the speed error ωerr as an input of a PI control and an operation of a compensated torque Tcom; and determining a torque variation based on the controller output Trm and a reference torque Tref and operating the torque variation in relation to an anti-windup gain Ka to use torque variation as an input of an integral (I) control. The method suppresses the speed ripple by compensating for the torque ripple through a controller which calculates the compensated torque by taking the signs of the speed error and the differential speed error into consideration.
