In electric vehicle control, system voltage stabilization control is executed to reduce the difference (”Vs) between a target value (Vs*) and detected value (Vsf) of a system voltage generated by a voltage boosting converter (21) for an AC motor (13, 14). Further, conversion power control is executed to reduce the difference (”Pi) between a command value (Pif*) and detected value (Pi) of the conversion power, which is defined as the output power of the voltage boosting converter (21). A conversion power correction quantity (Px) is computed from an input power operation quantity (Pm) of the system voltage stabilization control and reflected in the conversion power control to correct the conversion power. Thus, variations in a system voltage caused by an error or the conversion power control can be reduced. |
