| 摘 要： | 本文针对无速度传感器异步电机矢量控制系统，提出了一个基于卡尔曼滤波器的异步电机速度辨识方法。利用电机机端的定子电压和电流，运用卡尔曼滤波辨识速度。为提高算法的快速法，采用了降低观测器方法，该方法具有较高的精度，仿真结果表明，转速在全速度范围内都有较好的辨识精度。

| Abstract: | For a vector control of a speed sensor less induction motor drive system, a novel speed estimated method using an extended Kalman filter is proposed. The extended Kalman Filter is employed to estimate the speed of induction motor by only useing measurements of the stator voltages and currents. A reduced order state observer is proposed to improve the speed of the algorithm. Simulation resluts demonstrate that the filter is capable of estimating the rotor speed with a high accuracy in the whole range. |
