Abstract The temperature control of the drying room had been an important link in the coating process and had had a significant impact on the quality of automobile coatings. In this paper, aiming at the temperature characteristics and control difficulties of the automobile coating drying room, the control algorithm of fuzzy PID had been written in the PLC, and the temperature model of the drying room had been built in Simulink. Data exchange between the PLC and Simulink had been achieved through OPC communication, and the temperature response curve had been generated to conduct simulation verification on the temperature control system of the drying room. The Simulation results show that the fuzzy PID controller is superior to the traditional PID controller in terms of stability and adjustment time, and has certain application value in solving complex temperature control problems of the drying room.
