Additive state decomposition occurs when a system is decomposed into two or more subsystems with the same dimension as that of the original system. A commonly-used decomposition in the control field is to decompose a system into two or more lower-order subsystems, called lower-order subsystem decomposition here. In contrast, additive state decomposition is to decompose a system into two or more subsystems with the same dimension as that of the original system. Taking a system for example, it is decomposed into two subsystems: and , where and , respectively. The lower-order subsystem decomposition satisfies : By contrast, the additive state decomposition satisfies : ==Additive state decomposition on a dynamical control system== Consider an ‘original’ system as follows: where . First, a ‘primary’ system is brought in, having the same dimension as the original system: where From the original system and the primary system, the following ‘secondary’ system is derived: : New variables are defined as follows: Then the secondary system can be further written as follows: From the definition (), it follows : The process is shown in this picture: 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Additive State Decomposition」の詳細全文を読む スポンサード リンク
