Abstract
Background: This paper is devoted to adaptive feedback linearization based stabilization
of a two-axis gimbal platform.
Methods: A Lyapunov based adaptation mechanism is proposed for stabilization of a two axes gimbal
system through a feedback linearized control structure. The uncertainty of the products of inertia
is incorporated in the design procedure.
Results: The performed computer simulations demonstrate the robust performance of the proposed
two-axis gimbal stabilizer considering the cross-coupling effects between inner and outer gimbals.
Conclusion: The proposed control structure could be utilized in guided missiles, spacecraft, and
navigation systems.
Keywords:
Two-axis gimbal system, stabilization, adaptive feedback linearization, lyapunov based adaptation mechanism,
Line of Sight (LOS), loop controller.
