Modeling for Subway Station Temperature Control System of Urban Rail Transit Based on Predictive Control

Urban rail transit is an important research field in the public traffic, and the subway station temperature control influences the performance of subway ventilation greatly. To aim at the problem, firstly the principle, algorithm and characteristics of predictive control method is analyzed; then a subway station temperature control system of urban rail transit and its characteristics are researched; at last, modeling of subway station temperature control system is advanced by applied the generalized predictive control in the view of technology application in order to resolve the control problems caused by time-change, long-hysteresis, uncertainty and strong-coupling to meet the require of temperature control characteristic.
