Peltier thermoelectric modules (TEM) have a number of key advantages over compressor cooling systems (ease of use for both cooling and heating, high operational characteristics due to the absence of moving parts, etc.). Ensuring smooth and accurate regulation of the TEM temperature regime requires the development and application of effective automatic control systems. To create complex temperature change profiles, it is necessary to increase the order of the control system, which causes a stability problem. To analyze the stability of a trigenerative climate control system based on TEM, a mathematical model of the system in the form of transfer functions has been developed. The relations determining the conditions for the stability of the model according to the Nyquist criterion are obtained. As a result of the simulation, the stability regions of the system are calculated when the parameters of the component links vary. The directions for the further use of the proposed methodology for the subsequent optimization and synthesis of TEM control systems are determined.
