CONTROLLER FOR ROTARY AC MACHINE

摘要

FIELD: electricity.SUBSTANCE: controller for a rotary AC machine comprises an adaptive facility (7) of surveillance for output of a phase 00 of an estimated magnetic flow, a vector Isest of estimated current, a vector Phest of estimated magnetic flow and estimated speed wr0 on the basis of a vector Vsref of voltage control instructions, a vector ?Is of current deviation and a vector E0 of amplified deviation; a facility (8) for calculation of a vector of current deviation ?Is between the vector Isest of estimated current and the vector Is of detected current from a facility (3) of detection of current vector and a vector ?Phi of magnetic flow deviation between a vector Phest of estimated magnetic flow and a vector Phi of detected magnetic flow from a facility (6) of magnetic flow vector detection; and a facility (9) of amplification of deviation for amplification of a vector ?Is of current deviation and a vector ?Phi of magnetic flow deviation and release of a result as a vector E0 of amplified deviation.EFFECT: invention provides for smooth actuation from a low speed area comprising zero speed to a high speed area.12 cl, 23 dwg
