Liquid Tank Level Control with Proportional Integral Derivative (PID) and Full State Feedback (FSB)

This study discusses the control of the liquid level of a tank system using the Proportional Integral Derivative (PID) control and Full State Feedback (FSB) control. Tank systems are widely used in industrial processes and require a controller so that the liquid level follows the needs. Determination of PID controller parameters was sought by using Matlab's PID tuning feature. Meanwhile, the FSB parameters was determined using the trial and error method. The research results based on the Simulink Matlab simulation showed that the PID and FSB controllers could control the liquid level of the tank system and reached the reference value. However, the system's response with FSB control was better than PID control with faster settling time and smaller overshoot.
