Low-Bandwidth Fixed-Trim Control of a Guided Projectile

What is it about?

Guided artillery projectiles must use relatively simple, inexpensive control systems to keep costs low compared to other guided munition systems, such as missiles. To this end, we present a new projectile control method that allows for only a single, relatively slow actuator to be used. Our method exploits the tendency for the projectile to persistently pitch over, whereby the actuator is used to roll the projectile to direct the direction of the pitch-over if corrective steering is required, or spin the projectile otherwise.
