Synergetic Control of Magnetic Bearings in Artificial Heart Ventricle Rotor

This article reviews the problem of centering the rotor of an axial pump of the artificial heart ventricle (AHV) in a magnetic suspension. The small gap of the flowing part, high rotor speed, necessary service life of the AHV device, and its reliability and functionality introduce high demands on the control system of the rotor with magnetic bearings. This article proposes a synthesis of the control laws of the AHV with magnetic bearings based on the ADAR method (analytical design of aggregated regulators) of synergetic control theory and presents possibilities and prospects of applying the proposed control scheme. © 2016, Springer Science+Business Media New York.
