Consider the Bode diagram from Problem 11. Assume that the unity feedback closed-loop system is asymptotically stable. The velocity error coefficient K_v in numbers is: K_v =

Solution

Kv=lim sG(s)

The phase is constant at (-180) degrees (const is negative), the phase is 0 degrees up.

ess=A/Kv

Kv=0.6235
