Robust Control Solutions for Electric Vehicle Promotion Including Charging Infrastructure Development

In this paper the authors propose to determine the amount of public subsidies for the promotion of electric vehicles (EVs) by applying a feedback control model. The following three features are assumed on the growth model for the electric vehicle market for a controlled target: (1) The charging station is assumed to be public installation and private management; (2) The break-even point is calculated from the maintenance cost of the charging station; (3) The target numbers of electric vehicle sales are set as growth patterns. To achieve such target numbers and to follow the changes, we propose the application of robust control. In this research, an uncertainty is supposed in the model when the EV market growth is simulated, and fuzzy logic control is applied for better understanding by the decision-makers who exercise the policy measures and for the improvement of the target following capability. The simulation results show the effectiveness of the control based on the fuzzy logic even if some uncertainties are assumed in the growth model.
