Giridharan et al. (2002) studied Heart failure requiring ventricular assist device. Gain-scheduled proportional integral (PI) feedback controller was evaluated on Maintenance of average differential pressure between the left ventricle and the aorta. A gain-scheduled proportional integral feedback controller for ventricular assist devices successfully maintained physiologically adequate perfusion across various simulated cardiac demand conditions.
