摘要
针对直线感应电机初级漏感和次级漏感不相等的特性,提出了一种基于PWM逆变器的直线感应电机参数辨识方法,将堵转试验的等效电路改进后得到方程组计算电机的参数。将此方法应用于一额定电压30V的直线感应电机参数辨识中,试验结果与传统方法得到的试验结果比较,证明了所提出的方法提高了辨识精度。
The linear induction motor has the characteristic that the primary leakage inductance isn＇t equal to the secondary inductance, A parameter estimation method based on PWM inverter is proposed, which the parameters are obtained by solving a equation group from improved equivalent locked circuit.The proposed method is tested with a rated 30 V LIM and the experimental effects demonstrate that the estimating precision is advanced than us- ing conventional method.
