Design Of PID Parameter Self-tuning Thermostat Temperature Controller Based On Step Sesponse

The industrial large-scale production of high precision thermostat requires manual setting of complex parameters of temperature control system, which consumes a lot of labor costs and is low in efficiency. A PID parameter self-tuning thermostat temperature control algorithm based on step response identification is designed.According to the dynamic characteristic parameters of the step response curve of the prototype and the PID parameters, the linear regression analysis was carried out to obtain the parameter self-tuning model, and the auxiliary compensation rule table was used to control the power.Experiments on a real computer show that the algorithm is effective.
