Abstract: The paper considers the issue of approbation of the MPC-approach for the control of heating, ventilation and air conditioning systems, and also substantiates the possibility of improving the regulation process by its application on the example of a ventilation system. The principle of control using a predictive model is outlined, the features of control using the MPCcontroller are noted, the structure of the controller and the criterion for choosing the optimal values of the control signal are considered. The implementation of the MPC-approach is shown on the example of the supply VAV ventilation system in the classroom. To simulate the ventilation system in the Simulink environment of the MATLAB application package, the block diagram was developed, and the set of software tools Model Predictive Control Toolbox was used to synthesize the MPC controller. The study of transient processes the VAV ventilation system was carried out, the transient processes in the system without controller, with PID controller and MPC controller were compared. Comparison of the results showed that the use of the MPC controller makes it possible to improve the process of regulating the thermal regime in the room by increasing quality of regulation.

Keywords: microclimate, MPC controller, VAV ventilation system, temperature, transient process.
