本文利用Z-变换分析与综合“α-β”跟踪系统。文中首先阐明“α-β”跟踪系统的跟踪方程组与一种可能实现的方框图。其次,对“α-β” 跟踪系统的若干重要指标进行了分析,并从不同角度对动态参数α与β的值进行了选择。最后,本文利用变分法对“α-β”跟踪系统进行了最佳综合,并求得最佳跟踪方程组。
In this paper, Z-transform analysis and synthesis “α-β” tracking system. In this paper, we firstly illustrate the tracking equations of “α-β” tracking system and one possible block diagram. Secondly, some important indexes of the “α-β” tracking system are analyzed, and the values of the dynamic parameters α and β are selected from different angles. Finally, we use the variational method to optimize the “α-β” tracking system and find the best tracking equation.
