Effective safety control method for target attitude instability

The invention relates to an effective safety control method during attitude instability of a target, which comprises the following steps of: 1, acquiring sweep frequency information of a rudder system under different frequencies and different control plane tilt angles, and acquiring a roll angle and a roll angle speed of the target; 2, calculating a compensation angle according to the frequency sweeping information in the step 1, or calculating the compensation angle according to a steering engine model and the rolling angular velocity of a target; and step 3, calculating the tilt angle of each control surface of the rudder system according to the compensation angle in the step 2, and sending a tilt angle instruction of each control surface of the rudder system by a steering engine controller of the rudder system according to the calculated tilt angle information of each control surface. According to the effective safety control method during target attitude instability provided by the invention, target contr
