| Outline of Final Research Achievements |
In the field of ventricular assist devices, pump thrombus and control of appropriate flow rate have been issues to be solved. In this study, we have developed a method for detecting the pump thrombus from the phase difference between the current and displacement. Furthermore, we have also developed motor speed control system which can synchronize with the pulsatile of failure heart by using disturbance observer built in the magnetically levitated system.

本研究は，人工心臓装着患者の生存率向上および生活の質（QOL）向上に繋がる．特に，追加のセンサを用いずに制御系の変更のみで実装可能な点で，既存の磁気浮上型補助人工心臓にも適用可能であり，汎用性が高い．更に，磁気浮上システムを用いた生体信号のさんサレス計測という，新しい応用分野の発展にもつながる点で，学術的意義が大きい．
