Robust Control Design for a Two-axis Gimbaled Stabilization System

A two-axis gimbaled stabilization system in air vehicles must stabilize the line of sight toward a target against the external motion induced by air vehicle maneuvering and aerodynamic forces. It is well known that the target tracking and pointing performances of the air vehicles are largely affected by air vehicle motion decoupling capability. This paper introduces a servo drive model for a two-axis gimbaled stabilization system, and presents robust controllers for the air vehicle stabilization system. The simulation results are compared to confirm the validity of the suggested simulation model and the control design procedures for the stabilization system applied to an air vehicle.
