摘要
本文针对无速度传感器的异步电动机矢量控制、采用电压型解耦控制原理推导出异步电动机的简化等效模型．并根据这一模型提出一种利用电机转矩电流分量进行速度推算的方法。计算机仿真结果验证了其可行性。
?For speed sensorless vector-controlled induction motor drives, a simplified model of induction motorbased on voltage decoupling controt principle is derived. Then a speed calculation method using the torque componentof current is presented. Computer simulation results show that the proposed method is effective.
