عنوان مقاله [English]
In this paper an optimized high frequency lumped model of Induction motor is presented. Model parameters are identified and optimized using Genetic Algorithm (GA). A novel model and approach in an improved high frequency based on GA for parameter identification are used. At first parameters are limited and then fitted using GA for best fitting. The proposed model considered accurate simulation of both differential and common mode behavior in the EMI-frequency range from 100 Hz to 30MHz. model parameters which extracted from GA, is compared with experimental data in both magnitude and phase at the same time and results shown a good accordance between the experimental results and simulation results of the proposed model. A least mean square (LMS) method was used with a GA optimization method to solve the identification problem. The proposed model is suitable to obtain the simulation models for prediction of high frequency conducted Electromagnetic Interference (EMI), over voltage on terminated motor, and common mode current in cable fed induction motor.
