摘要
为降低无轴承同步磁阻电机系统总成本,缩小电机体积和长度,拓宽无轴承同步磁阻电机的应用领域,有必要省略位移传感器。文章提出无轴承同步磁阻电机电压模型法转子位移估计策略,对电机转矩绕组磁链进行观测,设计转子位移观测器,建立电机的无位移传感器控制系统。最后借用仿真软件验证系统的优良性能。
In order to reduce the total cost and to decrease the volume and shaft length of bearingless syn- chronous reluctance motor （BSRM）, and to expand the application fields for the BSRM, it is necessary to can- cel the rotor displacement sensors. In this paper, the rotor displacements estimation method based on voltage model is presented, the voltage model is used for estimating the flux in the torque windings, then the rotor dis- placements estimator is designed, and the displacements sensorless control system of BSRM is set up. Simula- tion results prove that the method can track the rotor displacements without sensors, the stable suspension op- eration and speed regulation are realized under condition of load disturbance.
