摘要
为适应雷达导引头跟踪高动态和高精度的应用需求,提出一种有界正相关自适应跟踪控制算法。通过分析指标之间的相互制约关系,构建一种积分系数与跟踪角误差变化大小正相关的自适应跟踪控制器;该控制器自适应积分系数多项式的拟合计算关联考虑隔离度指标、跟踪距离模式和最大跟踪角速度精度的指标要求。实测结果表明:采用该控制器,在满足隔离度指标要求的同时,跟踪10 (°)/s目标时,视线角速度精度提升1倍以上。
In order to meet the requirements of radar seeker tracking with high dynamic and high precision,a bounded positive correlation adaptive tracking control algorithm is proposed.By analyzing the mutual restriction relationship between the indexes,an adaptive tracking controller is constructed,in which the integral coefficient is positively correlat ed with the change of tracking angle error.The fitting calculation of the adaptive integral coefficient polynomial of the controller considers the requirements of isolation index,tracking distance mode and maximum tracking angle velocity accuracy.The experimental results show that when tracking 10(°)/s target,the line-of-sight angular velocity accuracy is improved by more than one time,while meeting the requirements of the isolation index.
