On the other hand, in the optimal origin reached control problem, an arbitrary initial state value is always reached to the origin subject to the performance index value of the quadratic form is minimized. In adobe mentioned the optimal origin reached control problem, Performance index value of system increases more than this value of the optimal LQ control problem. When we analyze this value, there are two methods. One is method of taking difference of value in each control method. And another one is method by theory of suboptimal control problem that uses mechanism of making to pattern. In this paper, we clarify degradation consistency in two methods theoretically and numerically.}, pages = {97--107}, title = {最適原点到達LQ制御問題の最適LQ制御問題に対する評価値劣化}, volume = {36}, year = {2007}, yomi = {サトウ, ヒロシ and ハシモト, シュウスケ} }
