Static controller for ventilation of highway tunnels

摘要

There are many large highway tunnels constructed all around the world. The operation of such tunnels has to meet several requirements, e.g. energy consumption optimization, minimal influence on the surrounding environment, lifetime conservation, minimal maintenance costs, portal protection from exhaust, etc. As the tunnel system is typically very complex (consists of a large number of fans, sensors, several ventilation shafts, etc.), a controller designed according to modern control design methods could be very efficient. The task of the controller is to keep the exhaust limits inside the tunnel below desired limits, with low energy consumption. We have decided to neglect the fairly complicated tunnel dynamics, and to design a static controller.
