摘要

Electrical control unit has been widely in all kinds of electrical systems. If it is interfered by external noises, it will affect the stable of whole system. In order to simulate the ECU, the impedance of ECU be measured by using Impedance Analyzer. The frequency domain impedances/admittances are fitted by Vector Fitting Method to approximate rational function. Based on the impedance synthesis theory, the equivalent circuits can be obtained. Then pspice/Spice model can be used to simulate the ECU. The simulation and experimental results have been given and compared. The results demonstrated the validity of method.
