Key result
The proposed PP-SMC control algorithm robustly tracked input signals in a cardiovascular model, driving the LVAD with flows between 1.7 and 5.7 L/min to prevent suction and over-perfusion.
Why the study?
LVAD technology requires intelligent control systems to optimize pump speed to achieve physiological metabolic demands for heart failure patients.
Does an advanced tracking control algorithm (PP-SMC) optimize LVAD pump speed to meet physiological metabolic demands in a cardiovascular system model?
