Abstract

This paper presents the design of a Proportional-Integral (PI) controller using the Programmable Logic Controller (PLC) techniques to control the temperature of water heated by oil fired heaters that are much used in Iraq. Our laboratory work consists of hardware part: the LOGO! V6 PLC, the thermostat, the analogue output valve and the oil fired water heater with its accessories while the software part includes Function Block Diagram (FBD) programming language of our PLC. The P and I parameters are found manually and their roles are also discussed in this paper. The designed control system can serve a precise way to control physical parameters within a desired range in the laboratory. In this paper, the authors focus on how the PI controller measures the temperature of the heated water in the oil fired heater and controls the aperture of the analog valve which controls the flow rate of the oil from the tank to the furnace of the heater according to the measured temperature.

Keywords: PI Controller, PLC, PID Tuning, FBD Language, Oil Water Heaters
