摘要
永磁同步电动机由于其固有的优点 ,得到了广泛的应用。本文讨论了永磁同步电动机调速系统中广泛采用的无位置传感器技术。无位置传感器可以分为两大类 :基于电磁关系和基于各种观测器技术的无位置传感器技术 ,目前主要的工作是提高调速精度和鲁棒性以及改善低速段的系统性能。
Because of its inherent merit, the permanent-magnet synchronous motor is widely used. This paper discus the mechanical-sensorless techniques, which are widely used in the permanent-magnet synchronous motor speed control system. There are two kinds of mechanical-sensorless techniques:the techniques based on electromagnetism relation and all kinds of observers. Today's work is to improve the precision of the velocity modulation and the robustness as well as the performance of the system in low speed region.
