Unformatted text preview: r damping ratio.
Let ζ = .7 METHOD 2
There are 3 unkowns (z, p, K) and only 2 conditions (equations). The system can again be
made to look "second order" if the pole is moved far enough to the left in the complex plan.
This will make the complex poles dominate
Try p = 10z
The overshoot will be too large so increase the damping ratio just to be safe
Let ζ = 0.707 Then from the settling time: adding some margin, let ωn = 4.9. The characteristic equation is: We want the characteristic equation to be the product of two factors, a couple of
conjugated poles (dominant) and a non-dominant real pole...
