Two-axis Gimbal System Stabilization Using Adaptive Feedback Linearization

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.
