|---|
| Abstract. Accurate thermal system modeling is critical for advancing control simulations and optimizing performance across a wide range of applications. Despite its importance, many existing studies rely on empirical models or provide limited explanations, hindering a deeper understanding of the modeling process. This paper highlights the gap in the field by analyzing existing works that used fuzzy-PID control in thermal system modeling, pointing out the lack of first-principles-based approaches. The paper presents an explanation of fundamental concepts such as thermal resistance and capacitance, illustrated with practical heat transfer examples. It then proposes that the plant in thermal systems should be viewed as two separate blocks: the actuator, which consists of electrical equipment and components, and the environment, represented as the compartment. The role of these components in control system design is discussed, emphasizing the need for distinct models of the actuator and environment for more accurate simulations and improved thermal regulation. This work underscores the need for a more systematic approach to thermal modeling, providing a clearer path for future advancements in both theory and practical applications. |
