Real Time Temperature Control System Using PID Controller and Supervisory Control and Data Acquisition System (SCADA)

Well designed conventional PID controllers using Ziegler-Nichols method are having large overshoot and settling time. Significant research work has been carried out to improve the performance of closed loop response with PID controller so that it can be used for real time temperature control system using SCADA(HC900 Honeywell controller). Also performance of PID controller is investigated for different performance metrics such as Integral Square Error (ISE), Integral Absolute Error (IAE), Integral Time absolute Error (ITAE), and Integral Time square Error (ITSE) is presented and simulation is carried out. Work in this paper explores basic concepts, mathematics, and design aspect of PID controller. Furthermore, after meticulous analysis of the operation of the plant, PID based schemes are formulated to control the temperature of UT_321 laboratory system, which gives satisfactory performance for various dynamics like low-and high-order, small and large dead time, and monotonic, oscillatory responses.
