AP5.8 A unity negative feedback system (as shown in Figure E5.11) has the loop transfer function Determine the gain that minimizes the damping ratio of the closed-loop system poles. What is the minimum damping ratio?
FIGURE E5.11 Unity feedback system.
Expert Answer
The closed-loop transfer function of the unity negative feedback system is given by: T(s)=G(s)1+G(s)Gc?(s)where G(s) is the open-loop transfer functio
