To control the simulated smoke flow field (used as a substitute for real fire smoke in the airworthiness verification experiments for aircraft cargo compartment smoke detection), this paper established a closed-loop flow control experimental platform for simulated smoke based on a full-scale aircraft cargo compartment mock-up. Control law design was conducted using MFAC theory. The closed-loop flow control effects of simulated smoke were verified with real fire smoke mass concentration as the control target. Additionally, the influence of control law parameters on control effect was explored. The experimental results demonstrate that MFAC method can effectively overcome the adverse effects of unmodeled dynamics in turbulent flow fields on closed-loop control, and achieve the approximation of the non-stationary flow fields between simulated smoke and real fire smoke. Compared with the PID control method, the control performance can be improved by more than 20%.
