摘要
针对复杂背景下目标图像跟踪要满足区域极点与滤波误差方差指标约束问题 ,根据满意控制与满意估计思想[1] ,利用线性矩阵不等式法将跟踪系统的鲁棒满意估计问题转化为线性矩阵不等式组 (LMIs)约束凸优化问题 ,给出了一种有效的满意滤波设计方法。通过这种方法进行满意波门设计 ,推演满意滤波算法 ,并以此对图像目标进行航迹跟踪实验 ,验证了相关结论。
For image target trace under complex circumstances with a desired circular pole index and a steady variance of filter error index,the idea of satisfactory control and estimation can be applied . With the LMI method, the robust satisfactory estimation of a stochastic trace system is turned to an optimization problem subject to a set of LMIs, and an effective method of design is presented to satisfactory estimation of the trace system. Satisfactory trace windows can be designed and an algorithm of satisfactory filter deduced through this method, and then use the algorithm for a track trace test of a missile image. Difference between satisfactory filter and Kalman filter can be visualized by simulation tests and analysis to check the relevant results.
