摘要
针对多普勒雷达测速模型具有不确定性和未知外部干扰的情况,建立了机载多普勒雷达测量飞机相对地球速度的状态方程,采用鲁棒H∞滤波器的线性矩阵不等式(LMI)综合方法,设计了鲁棒H∞滤波器。此滤波器不需要知道外部干扰和噪声的统计特性,并且使多普勒雷达速度测量的稳定性和适用性得到改善。计算机仿真表明了此方法的有效性。
To model uncertainty and unknown exogenous disturbance, the state model of the airplane speed measured by Doppler radar is proposed. Based on linear matrix inequality, the robust H∞ filter for this state model is developed. The filter has better robustness and accuracy. The stability of the measurement is improved. Numerical simulations are presented to show the capabilities of the approach.
