Principles of Construction of Microclimate Control and Management Systems in Agro-Industrial Production Based on Identification Algorithms

Abstract

One of the key problems in the agro-industrial complex (AIC) is the reduction of energy consumption. In order to increase the energy efficiency of agricultural production, the use of thermoelectric systems as microclimate control systems is promising. The quality of such systems largely depends on the level of applied technical and technological solutions and control and control algorithms. A generalized structure for the construction of energy-saving cooling and thermoelectric regenerative systems (TRS) to ensure the microclimate at agricultural facilities has been developed. The operator identification model of the TRS is constructed on the basis of parametric approximation of the temperature dependences of the system. The control algorithm of the TRS operation based on the identification method for multidimensional objects is developed. In order to test the proposed algorithm, a full-scale simulation of the control of a simplified TRS cooling module, namely a separate Peltier module RMT thermoelectric 1MS06-030-05, operating in active cooling mode, was carried out. The experiment has shown a significant difference between the transient’s duration of a correct (0.7 s) and defective (0.42 s) module RMT thermoelectric 1MS06-030-05 with a standard error of 0.068 s and a significance level <0.001 (t-value=13.622 for sample size 20). At the same time, the measurement of static parameters (resistance and Q-factor) did not reveal a 300 Kuzichkin O.R. et al. significant difference between a correct and defective module. In further research, it is planned to validate the proposed method by testing a wide variety of Peltier thermoelectric modules.
