Does not support clinical adoption of sensorless LVAD control; leaves open translation from animal models to humans.
A sensorless fuzzy logic controller for a rotary left ventricular assist system successfully optimized blood flow and prevented ventricular suction in simulations and animal models.
Choi et al. (2001) studied Heart failure requiring left ventricular assist system. Fuzzy logic controller for a rotary, turbodynamic left ventricular assist system vs. Traditional proportional-integral controller (in simulation) was evaluated on Delivery of blood flow without inducing suction in the ventricle. A sensorless fuzzy logic controller for a left ventricular assist system provided satisfactory flows at adequate perfusion pressures while avoiding ventricular suction in animal experiments.
