Model-based predictive ventilation control (MPVC) has the potential to increase the effectiveness of tunnel ventilation control whilst simultaneously providing operators with enhanced information in a user-friendly form. A method of using simulators in tunnel ventilation control systems is described. It is shown that the method has the potential for simultaneous improvements in the effectiveness of control and in the user-friendliness of interfaces with the tunnel operator. The improvements in effectiveness include reliability, stability and the utilisation of control targets based on conditions in the tunnel remote from sensors. The improvements in user-friendliness include access to evolving conditions throughout the tunnel system and the use of more physically-based parameters in all communications. The performance of the control system is illustrated with the aid of a virtual tunnel environment. It is shown to compare favourably with control based on a state-of-the-art methodology. Even greater advantages are foreseen in more complex tunnel systems.
