    摘要： A driving device controls a permanent-magnet synchronous motor having a permanent magnet in its rotor using a voltage-type inverter supplying drive power for the synchronous motor, makes the torque of the synchronous motor and the d-axis current flowing in the synchronous motor in the direction of the magnetic flux generated by the permanent magnet approach their own command values, and performs weakening field control by decreasing the d-axis current. To perform the above described control without complicated d-axis current command value operations or temperature amendments to motor constants, the driving device includes a proportional controller for outputting a d-axis signal proportional to the deviation between a d-axis current detection value and a d-axis current command value for the motor. A d-axis voltage command value and a q-axis voltage command value are determined according to the d-axis signal and a q-axis signal obtained based on the deviation between a q-axis current detection value, which is a component in the direction normal to the magnetic flux, and the torque command value for the motor. A voltage command vector is obtained from the d-axis voltage command value and the q-axis voltage command value. The voltage command vector is PWM-converted and a voltage-type inverter control signal is generated.

    摘要： An engine is activated to drive a generator when an electrical output is required. The required electrical output (PO) is searched and the necessary engine output is calculated. The basic driving point (NO, TO) which obtains maximum fuel efficiency is set at that output (S101-S105). The load of the generator is controlled so as to reach the set basic driving point. When the catalyst temperature is lower than a set value, while maintaining the required electrical output, the basic driving point is varied to a driving point (Ncold, Tcold) which will raise the exhaust gas temperature (S106-108). Furthermore when the temperature of the peripheral engine components in the engine room is higher than a set value, while maintaining the required electrical output, the driving point is varied to a driving point (Nheat, Theat) which will lower the exhaust gas temperature (S109-S111). Hence while maintaining the electrical output, it is possible satisfy each component temperature condition. Therefore while maintaining drivability, fuel efficiency performance, lowering exhaust gas emissions and component deterioration can suppressed.

    摘要： A fuel cell system and a related control method are disclosed wherein, during start-up of a fuel cell stack 1, a controller 21 operates a DC/DC converter 13 in a voltage control mode to allow an electric power to be supplied from a secondary battery 7 to a load 6 at an output voltage managed by the DC/DC converter. Under such a condition, an electric power level appearing when a voltage level of the electric power to be supplied from the secondary battery to the load lies at a value greater than an open voltage level of the fuel cell stack 1. Next, the DC/DC converter 13 is operative in an electric power control mode to allow the electric power to be supplied from the secondary battery to the load at a managed electric power output. Then, a level of the electric power to be supplied to the load is detected with the DC/DC converter 13, which permits the electric power to be supplied from the secondary battery to the load at an electric power level less than a resulting detected electric power level.
