Road tunnel ventilation system is of high non-linearity and uncertainty, and its exact mathematical model is acquired with very difficulty. In order to effectively control road tunnel ventilation system, a combined grey prediction fuzzy control (CGPFC) law is proposed in the paper. The output of this kind of combined controller is formed by combining outputs of the grey prediction fuzzy controller...
To control road tunnel ventilation is very difficult because of its high no-linearity and random property. In this paper the grey prediction and fuzzy control method is developed for road tunnel ventilation control. The method includes two prominent blocks, i.e., grey predictor and fuzzy controller. The grey predictor is realized based on discrete GM(1,1) and can rollingly predict the system outputs...
