Industrial premises as a dynamic element of the control system by the artificial microclimate

Abstract
The system of automatic control of the air conditioner is considered within the framework of a single computer-integrated complex with technological interconnections between the equipment of the air conditioner. An important dynamic element in the control system of artificial microclimate is the premises. In the work the mathematical model of the premises with lumped parameters for the synthesis and analysis of precision control systems by industrial inflow-exhaust ventilation installations and industrial complexes of artificial microclimate is developed, which takes into account the dynamics of heat-mass-exchange processes in the premises. Taking into account the presence of dynamic models of climatic equipment in a vector-matrix form (developed by the authors in previous works), for the stabilization of the microclimate parameters in the premises a dynamic model of premises in the space of states was obtained that allows the synthesis of a multidimensional regulator to stabilize the microclimate in the premises. The mathematical descript represents the dynamic properties of the premises for the main channels of influence. In contrast to the existing mathematical models, the proposed model of industrial premises takes into account mass-exchange processes, which allows to model the humidity of air mixture in the room. Dynamic model of industrial premises is represented by equivalent dependencies: a system of differential equations; in the space of states; by matrix transfer function. A significant advantage of the model in the space of states is the possibility of using vector-matrix mathematical apparatus for the synthesis, research and optimization of multidimensional control systems. An example of the simulation of transient processes for the premises by channels of influence is given.
