This paper presents a comparative study of three control strategies for optimizing hydrogen production from waste heat in cement plants: open-loop (no control), Proportional-Integral-Derivative (PID) control, and Model Predictive Control (MPC). The study uses simulation-based results to evaluate the energy efficiency, emission reductions, and operational stability of the system. The open-loop system, lacking feedback control, exhibited fluctuations in hydrogen production rate and temperature regulation, leading to inefficiency and instability. PID control stabilized the production rate but still showed minor fluctuations and occasional overshooting of the temperature, which limited its effectiveness under dynamic conditions. In contrast, MPC demonstrated clear advantages, maintaining hydrogen production at the desired setpoint while optimizing the system's overall efficiency. By anticipating future system behavior and adjusting control inputs dynamically, MPC showed exceptional disturbance rejection, particularly in handling variations in waste heat availability and external temperature changes. The results indicate that MPC leads to significant improvements in system performance, providing more reliable control, better efficiency, and enhanced environmental performance compared to both open-loop and PID strategies. This study highlights the potential of integrating advanced control strategies like MPC to optimize complex systems, offering a sustainable approach to energy management in energy-intensive industries.
