跟踪系统中跟踪器的延迟会对系统的稳定性和跟踪精度产生不利影响。为此以典型Ⅱ型系统为例,理论上定量地分析了跟踪器延迟对跟踪系统的影响,并提出了将采用LMS算法和横向滤波器结构的自适应滤波器用于延迟预测补偿的方法。仿真结果验证了方法的有效性。
Tracking the delay of the tracker in the system can adversely affect the stability and tracking accuracy of the system. In this paper, a typical type Ⅱ system is taken as an example to theoretically quantitatively analyze the influence of the tracking delay on the tracking system. The adaptive filtering method using LMS algorithm and transverse filter structure is proposed for the delay prediction compensation. Simulation results verify the effectiveness of the method.
