Abstract

The controlled dynamics of the rotor of an axial pump arranged in conical active magnetic bearings is studied. Bearings of this type make it possible to miniaturize the geometry of the rotor suspension structure, which is an important factor when designing ann auxiliary mechanical blood circulation apparatus. In such facilities, the problem of rotor positioning plays an important role. The essence of this work is in selecting the control coefficients of proportional-integral-differential control to stabilize the rotor.
