Thermoelectric coolers (TECs) are widely used to ensure a stable operating temperature of IR detectors, which are the main component of most optical electronic devices. Cooling improves such parameters of IR detectors as sensitivity, detectability, speed, range of spectral sensitivity, reliability, etc. TECs provide cooling on a temperature level of up to 190 K. Modern research is carried out in the directions of expanding the temperature range of the TEC and of increasing its coefficient of performance. The paper considers the use of optimal control theory in the simulation of TEC, matched with the parameters of the photodetector. The methods make it possible to determine the most suitable thermoelectric materials, optimal structure and optimal operation mode of TEC. Examples of TEC simulation for IR detectors by means of optimal control methods are given.
