一种电机转子位置控制方法及装置
摘要：
本发明适用于电机技术领域，提供了一种电机转子位置控制方法及装置，所述方法包括以下步骤：将采集得到的正确转子位置与出错时推算得到的转子位置进行比较，判断采集到的正确转子位置与出错时推算得到的转子位置的差值是否超出该电机转子位置变化给定范围；若采集得到的正确转子位置与出错时推算得到的转子位置的差值超出该电机转子位置变化给定范围，则舍弃此次采集到的正确转子位置；计算出错时推算得到的转子位置与该电机转子位置变化给定范围最大值的和值，用该和值作为纠正值控制电机的运行。本发明解决了现有技术中在电机转子位置连续出错时，直接使用采集到的正确转子位置来控制电机，使得电流的变化率过大而引起功率器件的损坏的问题。
摘要（英）：

The invention is applicable to the motor technical field and provides a motor rotor position control method and a device, the method comprises the following steps: the collected correct rotor position is compared with the rotor position calculated when in error, whether the difference value between the collected correct rotor position and the rotor position calculated when in error exceeds the given range of the motor rotor position change is judged; if so, the collected correction rotor position of this time is deserted; the total value of the rotor position calculated when in error and the maximum value of the given range of the motor rotor position change is calculated and used as a correction value to control the operation of the motor. The method and the device solve the problem in the prior art that when errors happen to the motor rotor position continuously, the collected correct rotor position is directly used for controlling the motor, thus causing the change rate of the current to be overlarge and damaging power devices.
