摘　　要：针对三自由度光电跟瞄平台系统状态不可完全观测的特点,进行可观测结构分解。对可观测部分设计H∞滤波器,并结合状态反馈H∞稳定控制对所设计的H∞滤波器进行仿真研究。结果表明,在噪声统计特性存在不确定性的条件下,H∞滤波器能很好地观测系统的状态,并且达到较好的滤波效果,具有一定的鲁棒性。Considering that it is impossible to implement complete observation to the states of the 3-DOF airborne electro-optical（EO） tracking and pointing platform, we made structural decomposition on the basis of the system＇s observability. An H∞ fiher was designed for the observable states of the system. And the designed H∞ filter was studied through simulation combined with state feedback H∞ stabilization control. The simulation results showed that：When there is uncertainty condition in the noise statistical properties, the H∞ filter can observe the system states effectively and achieve better filtering effect with certain robustness.
