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.
Abstract
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∞filter 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.
