Abstract
A liquid level control system was designed and fabricated to control the level of a liquid in a water tank that had a randomly varying inlet. Control of the water level was accomplished by adjusting a gate valve in the drainpipe located at the bottom of the tank. A solenoid actuator, operated in a continuous mode, controlled the gate valve opening and a pressure sensor provided liquid level feedback to the controller. Input to this system was a random flow disturbance consisting of water entering the top of the tank through three pipes controlled by solenoid valves and programmed to randomly switch on and off. The liquid level control system was implemented with a PC running National Instruments Lab View software allowing student interaction with the system. In conclusion, the system using a PC operated successfully and will be used as a teaching tool in a university class on feedback control theory.
