Process control is a common area of study for different engineering disciplines. Controllers working with the proportional–integral–derivative (PID) method are generally used in process control. Parameters like level, flow, position, pressure, and temperature are controlled in-process control. PID algorithm can be formed with different microprocessor-based devices. Process control is implemented by using analog input and outputs terminals of PLCs (Programmable logic controller) which is recently the most commonly used in industries. Also, a real-time PID method can be implemented by using a computer-based MATLAB
program in the laboratory.
The liquid level and flow control in the laboratory has been done by using PID algorithms and PLC device and MATLAB real-time interface by using an experimental set. Necessary connections and configurations have been prepared to perform process control. (SIMATIC Manager Step7) is used for programming in PLC. Besides, the MATLAB simulation program is configured to implement real-time control to be compatible with the MF624 data acquisition card. Liquid level and fluid flow control experiments were performed separately for the same PID algorithms formed on two different devices, then liquid level detection and liquid flow control results have been collected and investigated. Based on these results, a total of four experiments were compared with both devices considering the ease and difficulties of using PLC and MATLAB.
