| Outline of Final Research Achievements |
In this research, a control method considering the adverse effect due to the discretization constraint was developed for active vibration control of automotive powertrains necessary for improving the comfort and durability. The optimal dynamic quantizer, which has been proposed in previous literatures, was introduced into a conventional powertrain vibration control system to explicitly compensate for the effect caused by discrete-valued control inputs. For a limitation that should be satisfied in design of the optimal dynamic quantizer, a modeling-based-countermeasure was presented. The effectiveness of the proposed vibration control system was confirmed by the application to a powertrain system, which considers a real vehicle configuration.

| Academic Significance and Societal Importance of the Research Achievements |
自動車の動力を伝達する機構であるパワートレインの低周波振動は快適性や耐久性に悪影響を与えるため，開発現場におけるこの対策は製品価値を左右する重要な要素である．特に近年では，制御信号の伝達にCAN通信を使用する場合が多いため，通信時の離散化の影響も無視できない．本研究で提案した手法と知見はこれらの問題の解決に有効であり，自動車産業界の競争力向上に貢献できる．また，最適動的量子化器のパワートレインに対する適用例は申請者の知る限りこれまで無く，モデリングに基づく系統的かつ簡便な設計手法を提案したという点で学術的意義も有する．
