ON A CLASS OF ADAPTIVE PID REGULATORS

Abstract Based on some relations discovered between the deterministic servo regulator and the PID design a simple design role is presented for stable processes to ensure 5% relative overshoot for the closed loop step response. The adaptive solution is based on the explicit identification of a second order process model with time delay. Extending the PID regulator by an appropriate correcting term the poorly damped or inverse unstable process zero is allowed to be a zero of the closed loop system, as well. Additional pole placement is also available.
