Abstract: For the temperature control system with big inertia and delay, the design of the Fuzzy PID controller based on self-tuning parameters and fuzzy control theory is discussed. It is used in the temperature control system of BGA rework station. By simulation and comparison with other ordinary PID controllers, we conclude that the use of the method in the temperature control system can greatly improve the robustness and the dynamic and static properties of the system. It is simple enough for real-time control and can be easily used in the engineering practice.
