An Intelligent Robust Fuzzy Temperature Control of a Thermoelectric Cooler

摘要

Thermoelectric coolers (TEC) are used in a variety of applications that require extremely stable temperature control such as logical electronic processors, refrigeration equipment, air conditioning and scientific equipment. In this paper, the system dynamics of the thermoelectric cooler model including the cooling load heat exchanger and heat sink was driven. The dynamic model is presented with varying operating conditions. A proportional controller will be applied for the cold-end temperature control of a thermoelectric cooler. The feedback control system will be examined under variable cooling load and ambient temperature. An intelligent fuzzy controller was applied for the cold-end temperature control of a thermoelectric cooler. Fuzzy inference parameters which include the rule base and the shapes of the membership functions was tuned via simulation. The fuzzy control system was simulated under variable cooling load to assured its robustness.
