Abstract
Starting with a double integrator under analog PID control, various di scretization options are explored using Program CC. Asymptotic stabili ty is achieved in only three cases out of seven. The failures are expl ained. The analog controller is then redesigned by applying a lowpass filter to the derivative term, and asymptotic stability results in all seven cases, though with inferior dynamics in one.
