This experiment looked at the effectiveness of different process controllers (PID) in maintaining the liquid level of a tank that undergoes disturbances. Properties of proportional (P), derivative (D), integral (I), and combinations of these controllers were investigated when exposed to a set point change. Furthermore, the impact of tuning on the PID controller was studied using the Ziegler-Nichols optimization technique. The team concluded a tuned PID controller is an ideal process controller and should be implemented to maintain process operating conditions. They put their theory to practice at the UCI Infinity Fountain.
