Abstract: The energy consumption of highway tunnel operation is big. And tunnel ventilation accounts for a large proportion in the electrical ｌｏａｄ of tunnel. There will be great energy-saving effects if the frequency

conversion technology was applied to the tunnel ventilation system. But parameter setting is a difficult problem while controlling the system of frequency conversion ventilation by using PID control mode. To realize

the on-line self-tuning of PID parameters by combining fuzzy control and PID control mode. The control performance of the system will be better under different working conditions. Achieve the goal of energy saving

in operation.
