To improve control characteristics of an inverter while suppressing manufacturing cost. An inverter control deviceis a device for controlling an inverter devicehaving a plurality of switching elements. The inverter control deviceincludes a current control unitthat calculates three phase voltage command signals Vu*, Vv*, and Vw* based on a d-axis current command signal id* and a q-axis current command signal iq* at each predetermined calculation period T, a sampling period conversion unitthat outputs three phase voltage command signals Vu**, Vv**, and Vw** after update at each predetermined update period Tdifferent from the calculation period Tbased on a calculation result of the three phase voltage command signals Vu*, Vv*, and Vw* by the current control unit, and a gate signal generation unitthat generates a gate signal for switching-driving a plurality of the switching elements based on the three phase voltage command signals Vu**, Vv**, and Vw** after update output from the sampling period conversion unit

The invention is directed to modeling of heat and vibration for structures. Therefore, with a traditional model division for each component, one-to-one correspondence between the models and the components is not necessarily realized. There has been a problem in that it is difficult to divide the models. To solve the above problem, a simulation program according to the present invention includes a first model for calculating a first vehicle characteristics parameter, a second model for calculating a second vehicle characteristics parameter to transfer energy without converting the energy, and an interface model for performing conversion calculation of the first vehicle characteristics parameter and the second vehicle characteristics parameter.
