Improved Dynamic Performance of Temperature Sensor by Fuzzy Control
This article proposed one kind of fuzzy control method basing on the temperature comparison foundation. That basic thought of this method is to give thermocouple with electric current, and release or absorb thermal energy in the thermocouple node according to the electric current directions dissimilarity according to the Peltier principle, which causes the sensor to elevate temperature or decrease temperature, accelerates the heat change process, thereby enhancing the temperature sensor response speed. When the sensor is passed by the electric current in order to increase or decrease its own temperature, we have to know the actual measurement temperature. Additionally, the relationship between the sensor itself temperature change and the preceding electric current is complex. Therefore, we cant use the convention control method. Using the fuzzy control is completely decided by the fuzzy control itself trait.
