摘要
针对相对阶等于2这种非线性滤波问题中的典型情况,从理论上分析预测滤波器的稳定性;基于李雅普诺夫稳定性定理,证明了预测滤波器对系统未建模动态特性的鲁棒性,并确定了滤波残差的收敛界限。以无陀螺卫星姿态确定系统为例,通过仿真测试验证了预测滤波器的滤波性能。
Performance of the predictive filter in the typical case of the relative system order equaling to two is studied. The filter stability is analyzed, then the filter robustness in terms of unmodeled dynamics is shown based on the Lyapunov stability theorem and the convergent limit of the filter residual is determined. The good performance of the predictive filter is demonstrated through simulation results of the gyroless satellite attitude determination system,
