3 The loop transfer function of a single-loop feedback control system, is given as: s(s+2)(1+ ) it K as the horizontal axis and ra The parameters K and T may be represented in the vertical axis. Determine the regions in the T-versus-K parameter plane where the closed system is asymptotically stable and where it is unstable. Indicate the boundary on which the system is marginally stable.
