Modeling and Its H_∞ Stabilization Control for Airborne Electro-optical Tracking and Pointing Platform

LIU Shan-zhong, SUN Long-he, CHE Hong (School of Electronics and Information, Northwestern Polytechnical University, Xi’an 710072, China)  
According to the kinetic characteristic of three-degree-of-freedom airborne electro-optical tracking and pointing platform, the kinetic equation of three-axis platform framework was erected up, and moreover by predigesting and linearizing the model in the balance point, the math model was gained which could be the same with controller design. Applying the H∞ control which has good robustness connecting with Kalman filter, the controller of three-axis platform framework stabilization control was designed. Simulation research shows that H∞ controller’s control effect is good, especially when model parameter changes and multi-disturbance effects, the control effect is hardly affected. This indicates that the stabilization controller’s robustness is good, and its anti-jamming capability is strong, which fulfils the need of airborne electro-optical tracking and pointing system’s stabilization control.
