摘要
提出了一种基于空间矢量调制方式的异步电机参数辨识方法,可在电机静止状态下测量相关参数。该方法在考虑导通压降、开关延时、集肤效应和死区效应因素的基础上,提出了相应的补偿措施,提高了辨识的精度。并在以TMS320F28335为主控制器的异步电机无速度传感器矢量控制系统上进行实验,实验结果验证了该方法辨识的参数准确性高,可直接应用于无速度矢量控制系统。
An induction motor parameter identification method based on SVPWM is presented. This method can identify the parameters of the induction motor in a stationary state. Consideration of conduction voltage drop, time-delay switch, skin effect and dead-time effect is taken into to increase the accuracy of identification. The experiments were conducted on a sensodess vector control system based on TMS320F28335 and the results indicate that the parameters are accurate. And the speed sensodess vector control system performs well with the identified parameters.
