本文讨论了由直接Z变换和匹配Z变换所得数字模式分别与对应模拟模式的拟合精度,并给出了匹配Z变换数字调节器的设计方法,该方法是直接Z变换的推广,可用于数控系统设计中。
This paper discusses the fitting accuracy of the digital mode obtained by the direct Z-transform and the matched-Z transform respectively with the corresponding analog mode, and presents a design method of the matched Z-transform digital regulator. This method is a generalization of the direct Z-transform and can be used for numerical control System design.
