利用自适应卡尔曼滤波实现光电跟踪中的复合控制
Compound control of photoelectric tracking by using adaptive Kalman filtering algorithm
摘要
Abstract
In order to realize compound control for improving tracking accuracy in photoelectric tracking control system,a compound control structure based on adaptive Kalman filtering algorithm for model was established.Firstly,the angular position data of the target was compounded by taking advantages of tracking miss distance data and instrument position data;Then,the angular position data of the target was subject to filtering estimation in order to obtain angular velocity of the target by taking advantages of adaptive Kalman filtering algorithm for model;Finally,the compound control system was established by front feeding the angular velocity of the target to the velocity loop.The experimental result shows that target tracking accuracy is increased by 50％ after using the compound control system.Based on adaptive Kalman filtering algorithm for model,under the condition of keeping the stability of the original feedback control system,the tracking accuracy of the compound control system can be improved.关键词
