Research on an intelligent temperature controller based on on-line self-tuning parameters

According to the temperature control characteristic of the carbonyl compound mode evaluation device, the paper presents the design of system hardware and software, studies of control algorithm in combination with PID, pure delay and fuzzy control technology. The temperature controller is provided with dynamic tracks for quality and steady accuracy based on the PID control, and then an adaptive PID temperature controller will perform in a process control system, which can exert fuzzy control characteristics, such as high robustness, good dynamic response, short rising time and small overshoot. The application of the temperature controller with fuzzy PID to the said evaluation device has obtained a good effect.
