Abstract
In order to make the accuracy of temperature control of SIP chips in the aging test not affected by external interference and mathematical models, a paste-adaptive PID temperature control system suitable for the aging test of SIP chips was designed. By analyzing the influence of the changes of the two input variables of temperature deviation and deviation change rate on the aging test temperature, a fuzzy control rule table is established. The influence of control performance is completed, and the simulation and field debugging of the entire fuzzy adaptive PID temperature control scheme are completed. The test results show that the temperature control effect of the burn-in test based on the fuzzy adaptive PID control algorithm is 31.25% higher than that of the conventional PID control algorithm, and the anti-interference performance is improved by 66.6%.
