维纳滤波在模糊控制自动倒车GPS导航中的应用

Application of wiener filtering in fuzzy control of automatic reversing GPS navigation

随着汽车的快速发展,小车已成为多数家庭的代步工具,同时倒车问题也得到了广泛的关注。文章是通过模糊控制器来控制小车自动泊车,但是由于GPS定位中包含许多误差源(噪声),使得定位精度不精确,从而影响到汽车在自动泊车过程中的模糊控制器,使小车不能高效地倒入目标位置。为了解决由于噪声而产生的GPS导航误差,文章所采用的方法是通过维纳滤波来消除噪声,从而提高小车的倒车性能,最终得出实验结果并对结果进行分析。

Car has become a means of transport for most families with the rapid development of the car, at the same time reversing problem has been widespread concern. The article uses fuzzy controller to control automatic parking of car, but because the GPS positioning contains many error sources （noise）, so that the positioning accuracy is not accurate, which affects the fuzzy controller in automatic parking in the process, so that the car can＇ t efficiently reverse into the target position. In order to solve the GPS navigation error caused by noise, the method used in this paper is the wiener filter to eliminate the noise, so as to improve the performance of the car reversing, finally obtains the experimental results and they are analyzed.
