Level Control in a Water Tank

There are three process units: a water source that empties into a tank, a tank with a variable-flow outlet control valve, and a feedback controller. The controller controls the water level in the tank by sending a command to the control valve. The control valve is normally open and increasing command closes the valve. The controller has Proportional and Integral (PI) action with anti-windup. The diameter of the tank is 2 m.
