Abstract

Under the dual driving forces of deep penetration in Internet of Things technologies and iterative upgrades in user demands for environmental quality, intelligent temperature control systems have emerged as a critical platform for energy optimization in modern buildings. To address prevalent issues in conventional air conditioning systems including frequent temperature overshooting, insufficient thermal inertia compensation, and excessive invalid energy consumption, this study employs a PID controller as the core control methodology deeply integrated into the control logic of intelligent HVAC systems. An adaptive air conditioning control system was designed and developed based on an incremental PID algorithm. Through the construction of a second-order transfer function and optimization of proportional-integral-derivative parameter combinations using the Ziegler-Nichols tuning method, a compound control strategy with feed-forward compensation functionality was established. The results demonstrate the successful development of an intelligent HVAC system capable of automatically and precisely adjusting operational states according to indoor-outdoor environmental parameter variations. This research reveals that the synergistic interaction between the DHT11 sensor-based data acquisition mechanism and the PID control algorithm effectively resolves the coupled challenges of temperature hysteresis and energy redundancy inherent in traditional HVAC systems. The proposed methodology provides an engineering-transferable technical paradigm for energy efficiency optimization in smart home devices.
