| Abstract: | A transfer function model for automotive powertrain system under specific working conditions is built by using least square identification technique.Then the order of model is reduced with optimal Hankel minimum degree approximation.A simulation is performed and the results show that the model identification and order reduction have adequate accuracies.The modeling approach can be applied to the development of the throttle controller in vehicle speed automatic control system. |
