CONTROL APPARATUS FOR AC ROTARY MACHINE
First Claim
1. A control apparatus for controlling an alternating current rotary machine including a stator and a rotor, the stator having a coil wound thereon, in which at least one of said stator and said rotor is divided into at least two separate elements which are so configured that a phase difference representative of a relative position difference between one separate element and another can be varied in a circumferential direction, said control apparatus comprising:
- an actuator for adjusting a voltage induced in the coil of said stator, due to rotation of said rotors by driving at least one of said separate elements;
a magnetic flux command calculator for calculating a desired magnetic flux amplitude command based on rotating speed of said alternating current rotary machine;
a magnetic flux estimator for calculating estimated magnetic flux amplitude of said alternating current rotary machine;
a speed command calculator for calculating an actuator speed command to be given to said actuator so that the estimated magnetic flux amplitude follows the magnetic flux amplitude command; and
an actuator controller for controlling said actuator according to the actuator speed command.

Abstract
A control apparatus is for controlling an AC rotary machine which includes a first and second stator elements and a rotor, in which the first stator element can be turned, or offset, in a circumferential direction relative to the second stator element. The control apparatus includes an actuator for adjusting a voltage induced in a stator coil due to rotation of the rotor by driving the first stator element, a magnetic flux command calculator for calculating a desired magnetic flux amplitude command based on rotating speed of the AC rotary machine, a magnetic flux estimator for estimating magnetic flux amplitude of the AC rotary machine, a speed command calculator for calculating an actuator speed command to be given to the actuator so that the estimated magnetic flux amplitude follows the magnetic flux amplitude command, and an actuator controller for controlling the actuator according to the actuator speed command.
