An Airframe Stabilization System with State Observer and Correction Part for Terminal-Phase Missile Guidance

Anotace: In this paper an airframe stabilization system with state observer and correction part for a canard-controlled anti-aircraft missile is presented. The state observer based system is designed to be easy to implement and undemanding of significant onboard data processing and CPU resources. In addition, the correction part to improve the system's capabilities is described and an analytical method for determining its settings is proposed. The paper considers the terminal phase of guiding an anti-aircraft missile against an aerial target. This is of particular interest when considering the issues of combating the current means of air attack, characterized by high maneuverability, effectively. Robustness to disturbances in the signal processing paths and the ability to effectively stabilize the airframe is presented with extensive simulations of the proposed system using the Monte Carlo method.
