Additive state decomposition Additive state decomposition 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,
