Research on Wind Speed Control Strategy of a Subsonic Wind Tunnel

Wind tunnels are experimental equipment that artificially generate and control airflow to simulate the flow of gas around aircraft or entities, and are an indispensable component of the aviation field; And wind speed control is the core control part of wind tunnels, and the quality of wind speed control strategies will directly affect the various performance indicators of the wind tunnel. In order to achieve precise control of wind speed in a certain subsonic wind tunnel, the article designs a segmented wind speed control strategy based on the wind speed requirements under var-吕一仟
