Abstract To address the problem of temperature in the automobile drying room being easily affected by disturbances during the painting process, this study investigates the fundamental working principles and control process of the Active Disturbance Rejection Control (ADRC) algorithm. An ADRC control program was designed and implemented based on the Siemens TIA Portal PLC platform. A dynamic model of the drying room was built using the Simulink platform, and real-time communication with the PLC was established via OPC technology. This enabled real-time simulation of the automobile drying room temperature control system. The temperature response curve of the drying room was collected and compared with that of traditional PID control. The results show that ADRC outperforms traditional PID control in both dynamic response speed and control effectiveness, demonstrating its practical value in solving complex temperature control problems in drying rooms.
