Multi-Rate Digital Autopilot Modeling Methodology.

Abstract

This technical report presents the Multi-Rate Digital Autopilot Modeling Methodology used in the analysis of guided weapon system development programs within the Armament Division. This methodology evolved from many and varied autopilot analyses and has been refined as indicated in this report. Typical guided weapon programs that have used this approach are: Advance Medium Range Air-to-Air Missile (AMRAAM), WASP Antiarmor Missile, and Low Level Laser Guided Bomb (LLLGB). Reviews of both fundamental Z-Transform Theory and the Multi-Rate Transform are given. An example of a two-loop-per-channel autopilot typical of a symmetric missile is given. This autopilot is then modeled using Multi-Rate Transform theory to develop both open-loop and closed-loop transfer functions in the Z-plane. The computational algorithms used for Multi-Rate Modeling are referenced.
