Abstract.

The analysis of dynamics of rotor-driven artificial ventricle (VAD) was conducted in the work. A comparison of two types of control is given: a linear-quadratic (LC) optimization and PID-regulator. It was shown that LC – control allows the pump rotor positioning with an accuracy of 0.2 mm at speeds ranging from 5,000 to 12,000 rev/min.

Keywords: mechanical circulatory support, ventricle assist device, artificial heart, active magnetic bearings, dynamics of the control system, LC-control, PID controller, rotor stabilization.
