Fortified wine because he was inspired by a German wine flavoured with wormwood, an herb most famously used in distilling absinthe. However, wine flavoured with wormwood goes back to ancient Rome. The modern German word "Wermut" ("Wermuth" in the spelling of Carpano's time) means both "wormwood" and "vermouth". The herbs were originally used to mask raw flavours of cheaper wines, imparting a slightly medicinal "tonic" flavor. Vins doux naturels are lightly fortified wines typically made from white Muscat grapes or red Grenache grapes in the south of France. The production of vins doux naturels was perfected by Arnaud de Villeneuve at the
Additive state decomposition following relationship. From Table 1, additive state decomposition can be applied not only to linear systems but also nonlinear systems. Additive state decomposition is used in stabilizing control, and can be extended to additive output 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
