Nonlinear Control of Thermoelectric Peltier Moduls for Climate Management Systems in Agro-Industrial Complex

Due to the global shortage of energy resources and a sharp increase in their cost, the problems of energy conservation become more and more urgent. A promising approach to solving the problem of energy saving is based on the principle of trigeneration, which implies the simultaneous production of electrical and thermal energy and makes it possible to reduce the energy intensity of production and the cost of agricultural products. Based on this method, the structural diagram of thermoelectric climate control system and its equivalent functional model have been developed. Transient processes of the linear and nonlinear thermoelectric climate control system for agricultural facilities with various coefficients of two saturation blocks have been obtained using the MatLAB Simulink environment. From their analysis it was found that the use of nonlinear control has significant advantages over the linear control and can reduce the time of transients, dynamic control error and oscillation.
