Trajectory Tracking Technology of BTT Missile

The trajectory tracking system of BTT missile was studied. The nonlinear acceleration guidance logic was used on the outer loop to accomplish guiding. The acceleration autopilot was used on the inner loop; Design scheme and principle were discussed. The generating methods of the guidance and control instructions and the algorithm of calculating the parameters of guidance instructions were analyzed. The scheme was compared with the big circle route flight mode adding the attitude autopilot. The 6DOF trajectory simulation results show that the nonlinear acceleration guidance logic adding the acceleration autopilot can make the missile track the trajectory more rapidly and get well tracking effect. Its precision is obviously better than that of the big circle route tracking adding the attitude autopilot.
