“…The collateral damage, number of rounds used to intercept a given target and unit cost are also important facts for designers. To this end, several control mechanisms were recently proposed for the steering of these systems ranging from aerodynamic surfaces [9,16,19,24] to jet thrusters [3,7,11] or even inertial loads [18].…”

“…Collision-avoidance and formation-flight algorithms for airdrop of supplies from multiple units deployed in the same airspace have been derived and verified in simulation and experiment. 8 Guided projectile technologies have demonstrated [10][11][12] substantial progress recently. The emergence and subsequent gun hardening of Global Positioning System (GPS) technology has enabled precision artillery weapons.…”

SUPPLEMENTARY NOTES ABSTRACTThe hypothesis of this report is that delivery accuracy of small-diameter spin-stabilized projectiles can be improved through novel guidance and control techniques using low-cost components. A gyroscopically stable projectile equipped with a strap-down detector and rotary actuation assembly is introduced. Flight models are formulated to enable nonlinear simulation. The unique guidance challenges posed by characteristics of spin-stabilized flight dynamics such as limit cycles, center-ofgravity swerve, instability, and practical feedback are illustrated. New guidance and control techniques to circumvent these difficulties are proposed. Modeling, parameter estimation, and stability analysis results underpin control design. Representative feedback, control commands, and flight behaviors from nonlinear simulations demonstrate the efficacy of this guidance approach. Monte Carlo analysis shows more than a factor of two in accuracy improvement of the guided over the ballistic flight. These results indicate that delivery system improvements are achievable in small, gyroscopically stable projectiles containing low-cost guidance elements using integrated control formulations. iii SUBJECT TERMS
