Impact of Wind Speed Look-Ahead Mismatch on Carbon Dioxide-based IAQ Nonlinear MPC

Heating, Ventilation and Air Conditioning sector needs reliable control systems associated to Indoor Environment Quality. Indoor Air Quality parameters, e.g., carbon dioxide, cover a crucial role in this context. The present paper investigates the impact of wind speed look-ahead (previewing) mismatch on carbon dioxide Model Predictive Control. The considered case study is represented by an office characterized by two windows that allow natural ventilation. Natural ventilation is obtained through the manipulation of the windows opening. A nonlinear model is exploited for simulations and for control purposes. The carbon dioxide level represents the Controlled Variable while Disturbance Variables are occupancy and wind speed. The impact of wind speed look-ahead (previewing) mismatch on carbon dioxide Model Predictive Control is assessed through specific simulations on significant scenarios that take into account wind speed overestimation, underestimation, and exact knowledge.
