摘 要：In rotary left ventricular assist device（LVAD）,physiological control system is the element to automatically regulate the pump speed to ensure enough perfusion of *** this paper,the design of the physiological control system of rotary LVADs is reviewed first,such as criteria of physiological control system,sensors/signals,and control *** the design of an adaptive optimal controller for permanent LVADs is discussed.A Matlab simulation program and an experimental mock circulatory loop are employed as test environments for the *** physiological conditions,such as the variation of left ventricular failures and the variation of activities are simulated to study the performance of the designed physiological *** and experimental results consistently show that the abnormal hemodynamic variables of a congestive heart failure patient are restored back to the normal physiological range by the designed controller.
