摘要
针对基于“当前”加速度模型GPS动态定位数据处理中易出现的模型不确定性和噪声不确定性问题，提出忽略系统及噪声不确定性，根据H∞滤波算法建立滤波方程，对GPS进行动态定位，提高系统鲁棒性。为了提高系统精度，对“当前”加速度模型进行改进，通过实例分析表明，该方法计算量小，状态估计精度较高，系统鲁棒性好，对于际工程应用具有重要的现实意义。
Based on question that has easily appeared in the data processing not certainty and the noise not certainty question is fixed a position to ＂ present time ＂ acceleration model GPS＇s trends in accordance. It put forward neglecting system and noise not certainty. According to the filtration algorithm establishment filtration equation, it carries on the trends fixed position locations to GPS and H∞ robust filter is adopted. In order to raise the system precision, the model of＂ present time＂ acceleration is improved. By way of the living example analysis indicates that this method calculation capacity is small and can work with better precision and excellent robustness. The scheme can be put into practice easily.
