| 摘 要： | 根据测量和观测的定子电流、电压和磁链，提出了一种永磁同步电动机无传感器控制方案.对两相定子电压和电流进行测量和离散处理，在静止坐标系中通过计算磁链及其导数来估计转子位置和速度.转子位置角用于控制器中产生定子电流指令控制逆变器的滞环电流控制器.仿真结果证实了这种方法的可行性，该方法适合于从静止到额定转速的闭环控制，同时可消除由于积分导致的磁链漂移问题.

| Abstract: | A sensorless control strategy for permanent magnet synchronous motors is presented based on the measurement and observation of stator current,voltage and flux vector.Two phase voltages and two stator currents are measured and processed in discrete form.The rotor position and speed are estimated through the stator flux and its derivative in stationary reference frame.The rotor angle is used in a microcontroller to produce the appropriate stator current command signals for the hysteretic current controller of the inverter.The simulation results are presented to demonstrate the effectiveness of the proposed scheme. |
