Control of the Laboratory Model using PLC Controller

Abstract

This thesis deals with temperature control which is one of the important tasks in industry. It can be used for industrial applications like steel material processing. Nowadays industrial automation is mainly dependent on PLC. So, PLC based control technique is proposed to work with the temperature control system, where the temperature of the box is controlled by the input voltage of the bulb and fan acts as a disturbance to the system. System step response measurement and identification are done. Later, the step response is converted into transfer function and the controller tuning parameters are calculated. In this thesis, a traditional PID controller is used to achieve the overall control of the system and it is followed by visualization in HMI and data logging process. Both software and hardware design of the system is explained and analyzed in detail.
