Guidance and Control Design for a Class of Spin-Stabilized Projectiles with a Two-Dimensional Trajectory Correction Fuze

الملخص EN

A guidance and control strategy for a class of 2D trajectory correction fuze with fixed canards is developed in this paper.

Firstly, correction control mechanism is researched through studying the deviation motion, the key point of which is the dynamic equilibrium angle.

Phase lag of swerve response is the dominating factor for correction control, and formula is deduced with the Mach number as argument.

Secondly, impact point deviation prediction based on perturbation theory is proposed, and the numerical solution and application method are introduced.

Finally, guidance and control strategy is developed, and simulations to validate the strategy are conducted.
