摘　　要：根据三自由度机载光电跟瞄平台环架的动力学特性推导三轴平台环架动力学方程,通过对其进行简化并在平衡点线性化,得到适用于控制器设计的数学模型;采用鲁棒性好的H∞控制并结合Kalman滤波设计三轴平台环架稳定控制器。仿真研究表明,H∞控制器的控制效果良好,特别在模型参数摄动且有多种干扰作用时,控制效果几乎不受影响。这表明该稳定控制器的鲁棒性好、抗干扰能力强,满足机载光电跟瞄系统稳定控制的需要。Abstract： 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.
