This article discusses how to use MCU to achieve self-tuning temperature control, in particular, the feasibility of self-tuning control implemented on a single chip, as well as the algorithm convergence speed, robustness, anti-interference ability detailed analysis and comparison to Out of a simple algorithm for temperature control microcontroller, successfully developed a single-chip self-tuning control instruments. The results of real-time control show that this temperature controller can be applied to the system with the change of model parameters caused by external factors and other reasons, and the temperature control effect is obviously superior to the PID temperature controller, which makes a meaningful attempt for the intelligent instrument.
