Research on the control strategies of the 2.4m wind tunnel Mach number and stilling chamber total pressure control systems

Compared with all the other wind tunnels in our country, 2.4m wind tunnel is the first one of running with Mach number and stilling chamber total pressure controlled at the same time for all the tunnel running control. Considering the specific characteristics of the tunnel control systems, the possibility and feasibility of control strategies of neural control, adaptive mode following control, self-adjusting control, intelligent control and intelligent learning control used on wind tunnel are given out, and then, the actual control strategy is proposed. Actual running results are provided to illustrate the feasibility of the proposed control strategy.
