一种新型永磁同步电机用无位置传感器控制算法

Control Arithmetic of a New Type Permanent Magnet Synchro Motor Without Position Sensor

目前在永磁电机控制领域中,使用无位置传感器的电机调速方式获得了广泛的应用与发展。通过过去几十年的不懈研究,出现了多种无位置感应器控制算法,通常这些算法可以被归为两类,即仅适合于电机高速区使用的算法以及仅适合于电机低速区使用的算法,但是到目前为止,没有任何一种算法能够在电机的整个调速范围内部有效。本文提出了一种新型的融合了高速算法和低速算法优点的混合算法,该算法在电机的整个调速范围内部能有效的估算转子位置。

These days in permanent magnet synchro motor control field, the motor speed tuning mode without position sensor has been widely applied and developed. With the unremitting research in the past several decades several kinds of no-position sensor control arithmetic appeared. Generally the arithmetic can be classified to two sorts, arithmetic only fits the high speed range of motor and arithmetic only fits the low speed range of motor. However, none of the arithmetic is suitable for the whole range of motor speed. The article presents a new mixed arithmetic which combines the advantages of high speed arithmetic and low speed arithmetic. This arithmetic can effectively estimate the position of rotor in the whole speed range of the motor. fords.
