    摘要： In a controller for an electric vehicle, a voltage current phase difference calculating circuit calculates a vector phase .theta..sub.c from a voltage command value and the primary current of an alternating current motor. The vector phase .theta..sub.c is input to a second voltage command circuit which calculates a second d-axis voltage command value and a second q-axis voltage command value using the vector phase .theta..sub.c and d-axis and q-axis current differences. By correcting the voltage command value using the second d-axis and second q-axis voltage command values, the stability of the current control system is improved. By controlling the electric vehicle using such a system, a stable current control can be attained even when the electric vehicle is driven under a regenerative running state or a weak magnetic field control state.

    摘要： A power corresponding to an A/C voltage command id1* is applied in the d-axis direction of rotational coordinates of a stopped synchronous motor via a current control unit, a three-phase converting unit, and a power converter. Further, by using “an amplitude value of a current iq′ in the q-axis direction of the rotational coordinates generated in response to the A/C voltage command id1*” which is fed back and detected via a current detector and a dq converting unit, a field pole position estimation value &thgr;{circumflex over ( )} is converged. The field pole position is estimated by using the converged field pole position estimation value &thgr;{circumflex over ( )} as a true value of the field pole position &thgr; of the synchronous motor.

A control method for an electric vehicle having an inverter for supplying a direct current electric power from a battery to the synchronous motor, a smoothing capacitor, connected to the inverter in parallel for smoothing the direct current electric power, an inverter control circuit and an inverter relay for connecting and disconnecting the inverter and the smoothing capacitor to and from the battery. The inverter is controlled so as to prevent current from flowing into or flowing out of the inverter until the re-closing operation of the inverter relay is completed when the opened inverter relay is re-closed.

    摘要： An electric vehicle torque controller has a torque calculating unit and an actuate torque detecting unit. The calculated torque signal is compared with the actual torque to generate a torque compensation value, which is converted to a torque current signal. The torque current signal is used to a slip frequency, which is added to the output of an angular speed detector and used to set a secondary magnetic flux value. A secondary magnetic flux signal is generated according to the secondary magnetic flux value and the torque current signal. A secondary magnetic flux estimating unit generates an estimated secondary magnetic flux value, which is used to determine the exciting current. Primary motor current is controlled in response to the exciting current, the torque current, motor speed and slip value.

    摘要： A motor control device for an AC motor driven by a power converter with a maximum output frequency more than 500 Hz has a digital arithmetic unit which performs current-feed back control of the AC motor up to a maximum output frequency of the power converter, and outputs an AC voltage command to the power converter. The digital arithmetic unit includes a voltage control signal calculating unit for calculating a vector sum of the d-axis current deviation from a first subtracting unit and the q-axis current deviation from a second subtracting unit based on the d-axis and q-axis phases from a phase calculating unit as well as for calculating a d-axis voltage control signal and a q-axis voltage control signal according to the calculated vector sum, and performs current integration control for the d-axis and q-axis using the calculated vector sum as an input value. The AC voltage command is calculated based on the d-axis voltage control signal and the q-axis voltage control signals.
