To solve roll attitude real-time control problem for a 155 mm canard guided dual-spin stabilized projectiles, braking control model was proposed. According to trajectory correction theory and canards braking principle, the trajectory braking control model was given. The semi-physical simulation system was set up based on tow-axis flight simulation table, which can drive the dual-spin stabilized projectiles at different roll rate. The results show that braking model can rack roll attitude control-instruction under condition of 0.5 N·m disturb moment, and the nose portion can brake accurately at control roll attitude when the projectiles rotate at 100 r/s to 167 r/s. The braking precision and duration time can fulfill the need of guidance and control system.
