Abstract

A method of projectile control provides a control order for an organ allowing the yaw piloting of a spinning projectile. The control order causes a modification of a yaw piloting parameter of the projectile, the parameter that needs to be controlled being fin deflection. The angular rate of roll of the projectile is measured. At least one corrective coupling term is introduced into the evaluation of the control order modifying the yaw piloting parameter. The corrective coupling term is proportional to the angular rate of roll and also to the drift over time of the pitch piloting parameter to provide projectile piloting orders control fin motors.
