Subsonic transonic static pressure control method suitable for intermittent high-speed wind tunnel

The invention discloses a subsonic transonic static pressure control method suitable for an intermittent high-speed wind tunnel. According to the control method, a static pressure controller is adopted to take over wind tunnel static pressure control authority, disturbance correction of a model attack angle and static pressure serves as disturbance control quantity to be substituted into a model prediction controller of the static pressure controller, and corrected model prediction controller output quantity is obtained; and then a Mach number static pressure deviation correction algorithm is adopted to compensate the output quantity of the model prediction controller, the control deviation caused by inaccurate model and random disturbance in the model prediction control is made up, the raster indicator control quantity of the static pressure controller is finally calculated, and more accurate static pressure control is realized. By means of the control method, high-precision control over the subsonic transon
