Abstract: The optoelectronic stabilization platform is designed to isolate or compensate for the attitude changes of the carrier, thereby maintaining the spatial orientation stability of the payload. It plays a critical role in ensuring line-of-sight stability and rapid response for optoelectronic reconnaissance equipment. This study analyzes the performance bottlenecks and structural limitations of traditional stabilization architectures and investigates the control system of a novel five-axis optoelectronic stabilization platform. Corresponding kinematic and dynamic modeling methods are proposed and validated through simulations. The five-axis architecture consists of a three-axis inner gimbal stabilization mechanism and a two-axis outer gimbal follow-up structure. The new control system incorporates cross-torque transfer technology, voice coil motor arrays, a center-pivot-supported inner gimbal, and a novel vibration isolation system, significantly improving stabilization accuracy. Based on kinematic analysis and vector transformations, a coordinate conversion model between frames is established. Combined with innovative actuation methods, a dynamic model of the inner gimbal is developed, accounting for both internal and external disturbance torques as well as equivalent motor models. Co-simulation results using MATLAB/Simulink demonstrate that, compared to traditional two-axis four-gimbal stabilization platforms, the five-axis platform improves line-of-sight stabilization accuracy by an order of magnitude, effectively suppressing nonlinear friction and motion coupling issues. This research provides modeling methods and control strategies for the five-axis architecture applied to high-precision optoelectronic reconnaissance equipment, offering significant theoretical value and promising engineering application prospects.
