This paper deals with the robust feedback-control for the subsidy policy about the purchase of the plug-in electric vehicle (EV) and the business model of the charging stands. The controlled model has three characteristics: (1) A public institution builds the charge stands. (2) The break-even point is calculated by thinking about the maintenance cost and running cost. (3) The set value for the number that is spread of EV is given. However, the model has the uncertainties of the parameter, and a change by the influence of the economy and so on. Therefore, it is necessary to apply the robust control logic that overcomes the uncertainties of the model. We propose that the practice of the subsidy policy is regulated by feedback control. As the control logic, we use Sliding Mode Control. The simulation results show the advantage of a person planning EV purchase and the charge stand manager, and show that Sliding Mode Control is one of the control logic which is effective in the social model.
