You're a hero Chuck. This tallys well with the equations in Perrys book. What I was missing is the step where you get the transfer function. I made (attached) a little test rig. What isn't looking right is the underdamped behaviour. I was expecting to see a decaying oscillation around the top point. Maybe my test has errors. a.
