In　order　to　effectively　meet　the　requirements　of　smoke　confinement　in　different　fire　scenarios,　this　paper　proposes　an　adaptive　intelligent　smoke　control　method　combining　PID　(Proportional　Integral　Derivative)　system　with　a　traditional　air　curtain.　By　taking　a　tunnel　fire　configuration　as　an　example,　the　feasibility　of　PID-controlled　air　curtains　is　explored　and　the　calculation　method　of　PID　control　parameters　is　clarified.　The　stability　and　reliability　of　the　PID-controlled　air　curtain　in　realizing　the　smoke　control　effect　in　different　complex　fire　scenarios　are　studied.　The　method　of　determining　optimal　PID　coefficients　is　first　proposed.　Then,　the　robustness　of　the　PID-controlled　air　curtain　has　been　assessed　by　discussing　the　sensitivity　of　these　parameters　with　different　fire　scenarios.　The　results　show　that　the　PID-controlled　air　curtains　can　effectively　meet　the　requirements　of　smoke　control　in　different　complex　fire　scenarios.　The　impact　of　different　fire　scenarios　on　the　PID-controlled　air　curtain　system　lies　in　the　pre-control　period,　such　as　the　system　features　of　delay　time,　response　time,　overshoot,　etc.
