CONTROLLER FOR WINDING FIELD TYPE SYNCHRONIZER

摘要

PROBLEM TO BE SOLVED: To obtain a controller for a winding field type synchronizer, which can easily perform an appropriate control, reflecting the fluctuations of the properties of the winding field type synchronizer, even if the properties are fluctuated.

SOLUTION: The controller for a winding field type synchronizer comprises a flux command generating means 9 to generate a flux command Φr by inputting the number of rotation ω of the synchronizer 1, a flux estimating means 7 to calculate the magnitude ¾Φ¾ and the phase ∠Φ of armature inter-linkage flux Φ taking the flux of a permanent magnet into consideration based on an armature current and a field current value iff, a divider 15 to obtain an armature current command iδr by dividing a torque command ζr with the armature inter-linkage flux, a flux limiting means 11 to decide a field current command value ifr by the difference between the magnitude ¾Φ¾ of the armature inter-linkage magnetic flux Φ and the flux command Φr, and δ and γ axis current controllers 16, 18 to control so that the difference between the armature current iδf in the γ axis direction and the armature current command iδr becomes zero on the two γδ orthogonally crossed axes of the armature inter-linkage flux direction and the direction orthogonal to the direction thereof, and that the armature current iγf in the γ axis direction becomes zero.
