OVEN TEMPERATURE CONTROL USING PID WITH SMARTPHONE MONITORING VIA FIREBASE

Instrumentation and Control Engineering

This paper presents the development and implementation of an effective temperature control system for an oven using a PID (Proportional-Integral-Derivative) controller. The primary objectives are to achieve precise temperature regulation, reduce rise time (RT), minimize overshoot (OV) and settling time (ST), and eliminate steady-state error (SSE). System identification experiments were conducted to obtain an empirical model of the oven system, facilitating the tuning of the PID controller parameters. Various tuning techniques, including Ziegler-Nichols 1 (Z-N 1), Ziegler-Nichols 2 (Z-N 2), Cohen-Coon (C-C), Direct Synthesis (D-S), Internal Model Control (IMC), and Chien-Hrones-Reswick (C-H-R) methods, were investigated and evaluated. The PID controller parameters were determined to meet the desired performance criteria. Additionally, an IoT-based real-time data logging system was developed using Google Firebase, enabling smartphone monitoring of the oven temperature.
