Moreover, the cardiovascular pump is a very complex system that has no accurate model but much uncertainty and disturbance," scientists in Beijing, People's Republic of China report.

"Hence, the conventional control algorithm cannot achieve good performance. To overcome this problem, on one hand, a cardiovascular pump model is established.
