The frequency shaping method byH∞control is suitable for the problem. But we can't locate closed-loop poles in preferable region even if we use the robust stability-degree assignment method, because poles of weighting functions of the generalized system become undetectable modes. In order to overcome this problem, we use extendedH∞control combined with the robust stability-degree assignment method. By the method, we can design a controller that provides desirable frequency shaping and preferable closed-loop poles location at the same time. The performance of the designed controller is conformed by experiments., Article, システム制御情報学会論文誌. 18(7):261-267 (2005)}, pages = {261--267}, title = {拡張H∞制御による狭帯域周波数外乱の振動絶縁制御}, volume = {18}, year = {2005} }
