Abstract

Liquid level control in industrial applications is one of the classical control problems. The dynamic structure of two couple tank systems resembles many real systems such as boilers and oil refineries. It is the most controlled problem due to its non-linear structure and continuously changing phase properties. The liquid level of the tank is controlled by using a PI controller. The desired level is adjusted by using an ultrasonic sensor on the tank. The closed-loop system is operated by using a control interface designed by the Simulink program. The program prepared by Simulink is downloaded to Raspberry Pi over the Wi-Fi. The experimental input-output data of the system is provided by the external mode of Simulink. The user can adjust the speed of the fluid using the designed interface without a controller or control the liquid level by activating the controller on the same interface. This study provides great convenience to users to control and monitor the liquid level remotely.
