Abstract
A magnitude of current that does not cause electric power generation is supplied to a field winding of a movable element, and an induced voltage generated in a armature winding of a stationary element is measured. A position of the movable element is determined from the measured induced voltage. In addition to the thus-determined position of the movable element, a position of the movable element measured on a different basis is used to measure an error regarding the position of the movable element.
Claims25
An energy converter control apparatus for controlling an energy converter which has a movable element that has a field winding, and a stationary element that has an armature winding, and which is able to move the movable element by supplying an alternating current to the armature winding while supplying a current to the field winding, comprising:
- a controller that controls the current supplied to the field winding and the current supplied to the armature winding;
- and
- a measuring instrument that measures an induced voltage induced in the armature winding while the controller supplies a current that is at most a predetermined value to the field winding so as to move the movable element during the controller suspends supply of the alternating current to the armature winding.
An energy converter control apparatus for controlling an energy converter which has a movable element, and a stationary element that has a plurality of armature windings, and which is able to move the movable element by supplying a multi-phase alternating current to the armature windings, comprising:
- a controller that controls the current supplied to the armature windings;
- and
- a measuring instrument that measures a voltage of the armature winding while the controller supplies a current to the armature winding so that the current through the armature winding becomes zero during a state where the movable element is moving.
A method for controlling an energy converter which has a movable element that has a field winding, and a stationary element that has an armature winding, characterized by comprising the following steps of:
- supplying the field winding with a current that is at most a predetermined value and that is able to move the movable element during a state where supply of the alternating current to the armature winding is suspended;
- and
- measuring an induced voltage induced in the armature winding while the current is supplied to the field winding.
A method for controlling an energy converter which has a movable element, and a stationary element that has a plurality of armature windings, characterized by comprising the following steps of:
- supplying a current to the armature windings so that the current through the armature windings becomes zero during a state where the movable element is moving;
- and
- measuring a voltage of the armature windings while the armature windings are supplied with the current.
