【摘要】 给出了感应电机在两相静止坐标系中的数学模型,提出了一种无速度传感器矢量控制方案。该方案依据矢量控制理论,通过q轴磁通收敛于零辨识转速,取代了速度传感器。仿真实验结果证明了模型的正确性和调速方案的可行性。更多还原

【Abstract】 A mathematic model of induction motor under two static framework is presented and a speed sensorless control method is proposed,which,according to vector control theory,and by the q-axis rotor flux converging on zero for speed identification,has replaced speed sensor.The validity of the model and feasibility of the speed control method are verified by simulation results.更多还原
