Abstract
This manuscript presents the design, implementation, and evaluation of a microcontroller-based temperature control system for industrial furnaces using technologies available up to 2015. A proportional–integral–derivative (PID) algorithm was implemented on an 8-bit microcontroller interfaced with K-type thermocouples via an analog-to-digital converter (ADC). The system’s performance was benchmarked against open-loop control, demonstrating significant reductions in overshoot and settling time. Statistical analysis of performance metrics is provided. Key research gaps and future directions are identified.
