Worm-Drive Actuator Prototype for a Fin-Controlled Projectile

Abstract

This report presents a prototype actuator design for a fin-controlled projectile. The mechanical design is presented, followed by a description of the control-system architecture. The tuned control-system parameters are given along with results from bench-level experiments demonstrating the closed-loop dynamic response. Models are fit to the experiment response data to characterize the dynamic behavior, and the actuator is shown to meet bandwidth requirements.
