基于LMI的鲁棒滤波在无人机飞控系统中的应用

针对无人机在实际飞行过程中存在外界干扰以及传感器量测噪声的问题,应用线性矩阵不等式理论对无人机飞控系统进行了降阶鲁棒滤波器设计.讨论了适用于连续系统的降阶鲁棒滤波算法以及滤波器存在的条件.最后,进行了无人机纵向高度保持阶段的数字仿真,给出迎角与俯仰角速度的仿真曲线,仿真结果验证了该算法的合理性和有效性.

Application of Robust Filtering Based on LMI in UAV's Flight Control System

The influence of external disturbances and sensor measurement noise exists in the practical flight course of UAV.Linear matrix inequality theory is used to design the reduced-order robust filter for UAV's flight control system.The reduced-order robust filtering algorithm applicable to continuous system is discussed.And the condition of existence of the filter is also introduced in the dissertation.Finally,we carry the digital simulation about longitudinal height of UAV during retention period.The simulation...
