On Adaptive Control System for Multiobjective assist device

Abstract

This paper is concerned with a computer control design of blood pumps in multiobjective use—for extracorporeal circulation, cardio-circulatory assist and artificial hearts of total replacement type. The designed control system can implement constant control of blood pressure and/or pump output, and optimal control of cardiac work, wave form of blood pressure or driving pressure. Two experiments were made for test of system performance. The test resulted in precise adaptive control of hemodynamics under large variation of mechanical property of circulation.
