The output of this correctionsignal can be used to drive a simple auto-focus servo.
修正信号的输出可以用于驱动一个简单的自动聚焦伺服器。

The repetitive controller based on the theory of internal model produces correctionsignal based on the control error of the last cycle to eliminate the error in the latter cycle.
重复控制的基本思想是控制理论中的内模原理，根据上一周期的控制误差消除后面各周期性的信号误差。

Because array correction must be done for many times and a lot of array manifold information is stored, and correctionsignal source is provided, it is very inconvenient for the project implement.
