Remote gas pressure rapid accurate control method

The invention discloses a remote gas pressure rapid accurate control method. According to the remote gas pressure rapid accurate control method, when the distance between a gas pressure altitude simulator (a detection device) and an airspeed head (a control target point) is relatively long, gas pressure pipeline length L is relatively long, gas balance is difficult to achieve when control is realized by the gas pressure altitude simulator in a general mode, back and forth fluctuation of gas in the pipeline is caused, the gas pressure of an outlet of a total pressure sensor is represented by P1, the gas pressure of an inlet of the airspeed head is represented by P2, P2 is not equal to P1, and rapid accurate control of the pressure in the airspeed head can not be realized; a variable speed ratio control method is adopted, based on the dynamic rate adjusting function of the gas pressure altitude simulator, gas speed is controlled to reduce in an exponential model until rate of gas in a total pressure pipeline close to the airspeed head is reduced gradually to 0, so that stabilization of gas in the total pressure pipeline is achieved quickly, and P2 is approximately equal to P1. The remote gas pressure rapid accurate control method is capable of solving overshoot and oscillation problems of long time delay pipelines, realizing rapid accurate control of gas pressure of a remote target point, and satisfying detection requirements.
