| Abstract: | The article details calculation methods for determining optimal proportional-integral-derivative controller tuning across four distinct performance windows based on a process's lag-to-deadtime ratio. Topics include disturbance rejection tuning, critically damped tuning for setpoint changes; and minimum controller output movement tuning for deadtime-dominant processes. |
