Rocket attitude control loopback coefficient judgment method based on 1553B bus data

The invention provides a rocket attitude control loopback coefficient judgment method based on 1553B bus data. The method comprises the following steps: 1) carrying out screening processing on original 1553B bus data and extracting effective 1553B bus data; 2) extracting attitude control sprayer nozzle switch time point from the effective 1553B bus data; 3) searching attitude angle information of a jump point of attitude control sprayer nozzle control signal value in attitude angle information bus data and calculating the attitude control sprayer nozzle switch threshold; and 4) calculating the attitude control loopback coefficient and judging the correctness of the loopback coefficient. The method solves the problem of judgment of the correctness of the rocket attitude control loopback coefficient based on 1553B bus communication, and a quick and correct engineering application effect is achieved.
