Question

In the following block diagram, R(s)R(s) and D(s)D(s) are two inputs. The output Y(s)Y(s) is expressed as Y(s)=G1(s)R(s)+G2(s)D(s)Y(s) = G_1(s)R(s) + G_2(s)D(s). G1(s)G_1(s) and G2(s)G_2(s) are given by
A block diagram with two inputs $R(s)$ and $D(s)$. $R(s)$ enters a summing point with negative feedback from $Y(s)$. The result enters a second summing point where $D(s)$ is added and feedback from $H(s)$ is subtracted. The output of the second summing point enters block $G(s)$ to produce $Y(s)$.
