摘要：
The inductance and resistance of DC inductor are estimated based on the Levenberg-Marquardt algorithm and the response of LCR circuit to zero input current. The simulative results show that, immune to the data noise, the proposed method has higher parameter estimation accuracy than that based on the voltage-response Levenberg-Marquardt algorithm or the difference algorithm. Since the proposed method only acquires the inductor voltage signal and the circuit current signal, the DC inductor measuring system applying it operates easily. © 2016, Electric Power Automation Equipment Press.
