Research Abstract

研究成果は大きく分けて2分することができる。
1つはべき級数演算に関する研究成果である。べき級数演算に関する研究では、近似代数演算の考えに基づき、パラメータを含んだ数式をべき級数で表現する。べき級数は加減乗除が可能であり、一般的な数式と比較して取り扱いが柔軟に行えることから、パラメータを含んだ制御系の設計に対し、威力を発揮するものと考えられる。本研究では、べき級数演算にそのものに関する研究成果、およびその、H2およびH∞制御系設計等への応用を得た。
もうひとつの研究成果は、制御系設計上重要な量の代数方程式の根として表現、およびその応用に関するものである。本研究では、パラメータを含む制御対象の最適H2ノルム、またはH∞ノルム等を代数方程式の根として表現し、その表現を制御系設計へ応用した。
これらの研究結果は、パラメータを含むシステムに対する非常に有効な制御系設計手法、もしくは解析手法の基礎となることが期待できる。
