摘　　要：设计了一种用于电感参数辨识的高频响应电流处理方法,辨识出了电机的直、交轴电感参数,并且分析推导了逆变器非线性因素对电感参数辨识精度的影响。通过对响应电流进行两个延时滤波和两个同步轴滤波分析,剔除了基波和其他高频杂波,精确地得到高频电流的正、负相序幅值,辨识出了直、交轴电感参数。该在线参数辨识方法不仅在电机静止时能进行辨识,而且在电机正常运行的各个负载和速度下也能辨识出电感。电机实验结果表明,在不同负载和转速下的直、交轴电感辨识结果准确度较高,有助于电机驱动系统性能的改进。A method of high frequency current processing was proposed for inductance parameters identification.The d-axis and q-axis inductance parameters were identified.The effect of inverter＇s nonlinear factors on identification accuracy of inductance parameters was analyzed and deduced.The base current and other high frequency clutter current were excluding by applying two delay filters and two synchronous axis filters on response current.The positive and negative phase’s amplitude were obtained.The d-axis and q-axis inductance were identified.The proposed method could identify inductance in the stationary state and operating state of the motor.The results showed that under the different loads and speeds of motor,the accuracy of inductance identification was high.It could give a help for improving the real driving control system.
