Methodology for Analyzing Transient Regimes of Thermoelectric Systems with Several Nonlinear Links

Nowadays, Peltier elements and modules are widely used to control the temperature regime of various objects, generating electricity as sensors of various physical effects. For their effective use, the implementation of dynamic control of thermoelectric devices and systems is required, which is impossible without constructing an adequate model of their dynamic properties. Many works are devoted to the identification of linear and nonlinear characteristics of Peltier elements and modules. At the same time, little attention is paid to the problem of analyzing transient regimes of thermo-electric systems with several nonlinear devices under various control influences. A technique has been developed for the analytical calculation of transient regimes of the temperature response of TESs with several nonlinear links based on the operator method of piecewise linear approximation. An analysis of the characteristics of a specific system with proportional-integrating characteristics of inertia compensators and three nonlinear links (detectors and temperature controller) was performed.
