The sources of interference in computer-controlled systems are manifold and sometimes intricate.Generally speaking,according to the source,interference can be divided into internal interference and external interference.External interference is related to the environment and usage conditions of the system,and has nothing to do with the internal structure of the system.Internal interference is introduced by system structure layout,manufacturing process,etc.

计算机控制系统中干扰的来源是多方面的，有时甚至是错综复杂。总体上，按照来源，干扰可分为内部干扰和外部干扰。外部干扰与系统所在环境和使用条件有关，与系统内部结构无关。内部干扰则由系统结构布局、制造工艺等引入。
