摘要： A control apparatus for an AC rotating machine that can reliably and stably start up an AC rotating machine, particularly a synchronous motor using a permanent magnet, in position-sensorless vector control thereof, includes: a steady speed calculator that calculates, during steady state control of the AC rotating machine, a rotation angular frequency of the AC rotating machine based on an AC current and voltage commands; and a start-up speed calculator that calculates, during start-up control within a predetermined period after the AC rotating machine has been started up, the rotation angular frequency of the AC rotating machine based on the AC current and the voltage commands. The control apparatus corrects during the start-up control current commands so that the AC voltage amplitude of the voltage commands will be a constant value not more than the maximum output voltage of a power converter.

摘要： A hybrid-vehicle power generator control apparatus includes an integrated control unit that issues a driving command and a control command to an engine control unit and an electric-power conversion system control unit, respectively, based on requested electric power requested by a load apparatus, and a limiter that limits the control command from the integrated control unit such that when rotation frequency of an electric power generator is same as or lower than a predetermined value, the value of torque generated by the electric power generator becomes smaller than the value of torque generated by an engine. A limitation of the control command by the limiter prevents torques of the engine and the electric power generator from stepping out of the stable operating points.
