摘要： In a control apparatus for a rotating machine, an integration unit integrates a primary angular frequency based on an angular velocity command and computes phase, a power converting unit applies three-phase voltages to the rotating machine according to three-phase voltage commands, a current detecting unit detects three-phase currents flowing through to the rotating machine, a coordinate converting unit converts the currents detected by the current detecting unit into currents on rotating two-axis coordinates based on the phase output by the integration unit and converts voltage commands on the rotating two-axis coordinates into the three-phase voltage commands, and a voltage command computing unit computes the voltage commands based on the absolute value of deviations of the primary angular frequency and the current components along each of the rotating two-axis coordinates.

摘要： In a control apparatus for a synchronous motor, a coordinate converter converts a detected current into a current on rotational biaxial coordinates (d-q axis). A current controller outputs a voltage command on the coordinates so that the current follows a current command on the coordinates. Another coordinate converter converts the voltage command into three-phase voltage commands. An adaptive observer calculates an angular frequency so that a q-axis component of an estimated rotor magnetic flux is zero. An inverter applies a voltage to the motor based on the voltage command.

摘要： A control device for an induction motor controlling torque generation of the induction motor with high precision includes a rotation speed detector which detects the rotation speed of the induction motor, a current detector which detects a primary current of the induction motor; an amplifying unit which amplifies deviation between an estimated primary current obtained from a magnetic flux observing device and the primary current obtained from the current detector; a magnetic flux observing device which estimates an estimated secondary magnetic flux and an estimated primary current of the induction motor based upon the rotation speed obtained from the rotation speed detector, the primary voltage of the induction motor and the deviation signal obtained from the amplifying unit, and a control unit which controls a voltage applied to the induction motor based upon the estimated secondary magnetic flux obtained from the magnetic flux observing device. In this arrangement, the amplifying unit amplifies the deviation of the primary current based upon feedback gains consisting of eight respectively independent factors. Thus, it is possible to provide torque control with high precision even at the time of low-speed operation.

摘要： In the synchronous motor controlling apparatus and method of the invention, a current is detected and subjected to coordinate transformation onto &ggr;-&dgr; axis assumed for the rotor. A correction term is obtained on the basis of the derived current and an arbitrarily given correction current instruction. A &ggr;-&dgr; axis voltage instruction is computed by adding a value obtained by multiplying the correction term by a proper gain to a voltage equation in a steady state of the synchronous motor. Consequently, a control method of small computational load, which does not require gain adjustment according to the inertia of a motor load, can be attained.
