This paper investigates the suitability of using a gimbaled rotor actuator for trajectory control of a projectile. In this novel concept, a single-gimbal variable-speed control moment gyro is used as the sole control actuation system, allowing actuation in two orthogonal directions and two-dimensional control over the projectile’s flight path without any moving aerodynamic surfaces. A complete nonlinear model of the eight-degree-of-freedom rotational and translational flight mechanics is developed, as well as an accurate aerodynamic model for short-range trajectories. Linear models are derived for control design, and controllers are synthesized along with a steering logic to achieve control of the projectile’s roll and sideslip angles. Successful tracking of both angles is demonstrated, and a large course deviation is achieved, showing significant maneuverability and proving the viability of the concept.
