Abstract
An adaptive control system for driving the left ventricular assist device (LVAD) is developed. The system regulates the outflow volume from the LVAD, avoiding thrombosis and hemolysis, and minimizing the driving energy. The weighted least square one-step-ahead adaptive control algorithm was applied to the slopes of the positive and negative pressure characteristic curves in the relationship between the stroke volume and the systolic duration. It is proved that the stroke volume and the systolic duration can be regulated independently, satisfying the optimal driving condition.
