Fuzzy Control Applied to Drainage System of City Highway Tunnel

For drainage system of city highway tunnel is nonlinear, large time lagged and hard to be simulated by accurate mathematical model, we design a fuzzy controller. Water level and water level´s change rate are input parameters of the fuzzy control system, and they should be taken into account together. The number of water pump which should be turned on is output parameter of the system. We use Matlab to simulate the fuzzy control system and get the surfview of the fuzzy controller.
