Tuning a PID Controller
You have 2 right-half plane zeroes : 0.012 and 18. The zero at +18 is &quot;fast&quot; and will not affect the performance much, but your slow zero at 0.012 will severely limit your performance. You can't cancel this right-half plane zero with a right-half plane pole in your controller, your controller output will be unbounded.
Is this homework or a real life problem?
