The problem asks for a 20% overshoot, and the damping ratio corresponding to that is 0.456. The book says we have to drag the poles in MATLAB until we get our desired damping ratio shown at the bottom, and then the poles are there (-1.79+-3.5j) Is there a way to do this completely by hand...

Is it simply: Gol = ##\frac{K}{(s)(s+6)(s+10)}## Gcl = ##\frac{Gol}{1+Gol}=\frac{K}{s^3+16s^2+60s+k}## s^3+16s^2+60s+k = 0 What do I do from here?

Homework Statement Design a lag-lead compensator for the system of Figure 9.37 so that the system will operate with 20% overshoot and a twofold reduction in settling time. Further, the compensated system will exhibit a tenfold improvement in steady-state error for a ramp input. Homework...
