CONTROLLER FOR ROTARY AC MACHINE Russian patent published in 2013 - IPC H02P21/00 H02P21/14 H02P27/04 

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 ΔIs of current deviation and a vector E0 of amplified deviation; a facility (8) for calculation of a vector of current deviation ΔIs 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 ΔPhi 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 ΔIs of current deviation and a vector ΔPhi 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.
