摘要
电磁干扰是一种复杂多变的随机过程,为提高控制系统在工程应用中的抗干扰能力,详细论述了控制系统在工程应用中最常见的电磁干扰的分类、干扰的耦合途径及控制工程中抗干扰的基本途径。控制系统在工程中遇到的大多数干扰往往源于那些基本的干扰和基本的耦合途径,在工程设计阶段,考虑干扰的抑制问题,可供采用的方法多且直接简单。
Electromagnetic disturbance is a kind of complicated and stochastic process. To improve antidisturbance capability of control system in engineering application, the classification and couple way of electromagnetic disturbance, as well as, basic way for anti-disturbance in engineering is introduced in detail. The most disturbance of control system in engineering is due to basic disturbance and basic couple way. In engineering design phase, there are many simple and direct means and methods for controlling the disturbance problem.
