The control system for mechatronic unit of implantable left ventricle assist device

Abstract

The work is dedicated to the development of control system for implantable left ventricle assist device based on mechatronic units. An algorithm for determining the control parameters is described. A comparative analysis of different types of step-control law on energy consumption is conducted. Three variants of implementation of the control system based on the proposed functional diagram are considered; their comparative evaluation is provided. The results of the dynamics simulation of the mechatronic unit are present. The control law, which provides the required dynamics in cardiac output, is defined. A tabular variant of control algorithm implementation of mechatronic module is offered. The hardware implementation of digital control system is described.
