For a closed-loop system, consider the followng transfer functions. process Gp(s), controller Gc(s), measuring device Gm(s), and final control element Gr(s) [5] G,(s)=7s+12;G((s)=2;Gm(s)=1;Gf(s)=1 Detemine the offset in the closed loop response due to a unit step change introduced in the set point of the output variable Options
