Low-Cost Actuator Dynamic Model and Controller Development for Gun-Launched Munitions

Abstract

The US Army's modernization priority of long-range precision fires has highlighted a need for low-cost, high-g survivable, fast-responding munition control actuation technologies to enable range extension and terminal maneuvers. This report focuses on research into independent canard control actuator technologies based on commercial off-the-shelf servomotors. Linear and nonlinear actuator dynamic models are presented, and the model parameters are estimated from open-loop experiment results. An optimal, model-based controller is developed for the actuator. This controller was implemented in hardware, and an experiment was performed to demonstrate the closed-loop response of the actuator satisfies the design requirements.
