Abstract : We consider the problem of regulating the air quality in underground extraction rooms for mining industry. Based on distributed measurements, the goal is to minimize the energy consumption associated with the ventilation system to fulfil environmental constraints while ensuring thresholds on the admissible pollutants concentrations. This is clearly a challenging control problem where the flow dynamics, the interconnections between subsystems and the time-varying topology have to be taken into account along with real-time computation constraints. In this paper, we first describe a real-time simulator based on simplified flow dynamics, which is used in a state-feedback control scheme that motivates model-based control strategies. An online parameter estimation algorithm is proposed to adjust the control-oriented model (pressure dynamics) output to the distributed measurements. A new approach based on time-delay systems is finally introduced to model the convective phenomena.
