WebThe transfer function of G(s)= s^2 +s +4/s(s-1)(s+1) is in a closed loop unit negative feedback system with a compensator of gain K. Use Nygist criterion to find the values of K for which the system will be stable and check your result using the Routh-Hurwitz criterion and a root locus plot. WebMar 17, 2024 · Consider that a unity feedback system is defined by the open-loop transfer function shown in equation (10). The factor by which the transfer function, gain K, can be multiplied to make the system marginally stable is called gain margin, GM.
