摘要： 讨论一种典型的采样控制系统──直接数字控制（ＤＤＣ）系统（简称数控系统）在Ｓ域和Ｐ域的分析设计方法。根据采样控制系统理论，从数控系统在Ｚ平面的稳定性判据出发，利用ｔｕｓｔｉｎ变换（Ｐ变换），通过Ｚ平面、Ｓ平面和Ｐ平面之间的映像关系，导出数控系统在Ｓ域和Ｐ域的稳定性判据，进而提出了数控系统在Ｓ域和Ｐ域的分析设计方法，并详细说明了这两种设计方法的具体方法与步骤。

Abstract: This paper discusses a method of analysis and design in of a typical sample control system-direct digital control(DDC) system S and P domains.According to the theory of sample-data control systems, by starting from the stability criterion of digital control system in Z-plane and using tustin transform(p-transform) and the relations between Z-plane,S-plane and P-plane, the stabitity criterion for digital control systems in S and P domains is conducted.Further more,the analysis and design method digital control systemsin S and P domains is put forward.
