    摘要： A synchronous motor control system includes a synchronous motor 1, an inverter 3 and a controller 4 wherein a current differential detecting unit 13 detects a variation of a motor current when the three phases of the motor 1 is short circuited by the inverter 3, namely at the moment when a carrier wave in a PWM signal generator 9 assumes maximum or minimum value, in a calculating unit 14 a phase &ggr; from &agr; axis of a stationary coordinate system to a three phase short circuited current differential vector is calculated, a phase &dgr; is estimated from d axis to the three phase short circuited current differential vector by making use of d axis current id and q axis current iq on d-q axes coordinate system in the controller 4, thereafter the magnetic pole position &thgr; with respect to &agr; axis is calculated from the phases &ggr; and &dgr;, based on thus calculated magnetic pole position &thgr;, d-q axes control units 11, 7 and 8 are constituted to control the synchronous motor, thereby a highly reliable control system for the motor which permits a detection of the magnetic pole position without affecting a state of applied voltage thereto while performing a usual PWM control with a low cost controller.

    摘要： This invention aims to realize a superior control system for electric automobile, wherein the current can be accurately controlled according to the state of the automobile and yet high driving performance and charging performance can be achieved. When in the drive mode of the automobile, the system detects the current for drive using the current detector, controls the current of the inverter, and drives the induction motor. When in the charge mode, the system detects the current for charge using the current detector, controls the inverter, and charges the battery with the current from an external power supply. The intensity of the current differs by several times when driving and when charging, but the current detection range of the current detector for drive is wider than the current detection range of the current detector for charge. Therefore, the system detects higher current very accurately when driving and detects lower current very accurately when charging. Either when a charge control is required or when a motor drive control is required, the system can perform accurate current control suitable for each current control range requirement, thereby allowing highly efficient charge control with less noise.

    摘要： The invention provides an electric power converter system which uses a standard low-priced control processor and is suitable for improving the voltage utilization factor in the output voltage. D-axis and q-axis voltage commands and a rotation angle .theta. defining a voltage command vector on a rotating coordinate system are input to a voltage calculation circuit. The voltage command vector is transformed in a rotating coordinate transformation unit into a .alpha. axis and .beta. axis voltage commands to be defined relative to stationary coordinate system. A judgment unit determines which section contains the voltage command vector, from among three sections on the stationary coordinate system having one axis thereof (.alpha.-axis for example) coinciding with one axis of the three phases. A three phase voltage generation unit then selects a method of calculation on the basis of a result of the section determination, and calculates three phase voltage command values respectively utilizing the .alpha. axis and .beta. axis voltage command values. Since calculation requires only a simple add/subtract and shift operation, a high performance economical power converter system which improves the voltage utilization factor substantially can be realized.

    摘要： When a voltage level determinator judges from the terminal voltage of a smoothing capacitance that a battery is in an over-charged state and cannot receive regeneration energy, a regeneration/free-wheel mode selector switches to a free-wheel mode for consuming the energy of the battery. For this purpose, a torque reducing signal generator executes a control in which only a magnetizing component of current flows through the primary winding and no driving force is generated in the motor, with the result that the energy of the battery is consumed as heat loss inside the motor. Then, when the over-charged state is eliminated and the energy receiving capability of the battery is recovered, the regeneration/free-wheel mode selector switches the mode to the regeneration mode to obtain regeneration braking.

    摘要： The invention provides a control apparatus for an induction motor to maintain torque following controllability even with use of inexpensive speed detection units having detection delay. In a control unit, a phase correction arithmetic circuit uses a motor speed detection value detected by a speed sensor and a low-pass filter and a detection delay time of a control system to compute a correction phase. An adder adds the correction phase to a magnetic flux phase obtained by a vector control computation. The addition corrects a magnetic flux phase deviation due to detection delay of the correction phase of a primary current command, and compensates for the detection delay so as to maintain the torque following controllability of an inductor motor.
