Abstract
A method including: setting a weighting function based on an amount of change in impedance of a control target; and determining, for a power controller, a transfer function composed of a transfer function of an internal model obtainable by performing Laplace transform on the voltage reference value and a transfer function of a partial controller, the transfer function of the partial controller being for outputting the control output after receiving, as an input, an output of the transfer function of the internal model, wherein the determining includes determining the transfer function of the partial controller using an H∞control theory so as to reduce (i) a first amount of control obtainable by multiplying the control output and the weighting function and (ii) a second amount of control that is an output of the transfer function of the internal model.
