Application of Modern Control Theory and Adaptive Control Concepts to the Guidance and Control of a Terminally Guided Anti-Tank Weapon,
Abstract
The advent of the microprocessor makes feasible the implementation of more complex guidance and control algorithms than were possible with analog autopilots. The purpose of this study was to demonstrate the increase in system performance possible through the application of such laws to an existing weapon system while requiring no changes to the airframe, sensor complement, actuation system, or rocket motor. The goal is to have the performance of the resulting system limited only by physical plant constraints such as seeker rate capability, gimbal limits, maximum fin deflection, total impulse of rocket motor, or structural strength. For this study, advanced control concepts were applied to four aspects of guidance and control: terminal guidance for large initial offsets, trajectory control for maximizing the vertical impact angle, airframe stabilization and actuator control. The weapon system considered was the laser-guided HELLFIRE missile, although the design concepts are applicable to other systems.
