ABSTRACT:
In electric vehicle control, system voltage stabilization control is executed to reduce the difference between a target value and detected value of a system voltage generated by a voltage boosting converter for an AC motor. Further, conversion power control is executed to reduce the difference between a command value and detected value of the conversion power, which is defined as the output power of the voltage boosting converter. A conversion power correction quantity is computed from an input power operation quantity 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.
