摘　　要：针对窄带高功率微波(HPM)强电磁环境对控制系统的性能影响,采用理论分析和实验测试等方法对电磁干扰(EMI)的干扰源和耦合途径进行研究,提出控制系统电磁兼容性的设计方法,从电磁屏蔽、滤波和接地等方面进行分析并采取措施。实验结果验证了控制系统在屏蔽、滤波和接地等方面采取的措施,对抑制窄带HPM源强电磁环境下的电磁干扰有效可行,控制系统的设计满足HPM源的工作要求。同时窄带HPM控制系统的电磁兼容性(EMC)分析和设计也为强电磁环境下仪器设备防护加固提供技术支撑。In allusion to the influence of narrow-band high power microwave（HPM） source electromagnetic environment on performance of control system, the interference source and coupling paths of electro magnetic interference（ EMI） are researched through theoretical analysis and experimental measurements. Electro magnetic compatibility（ EMC） design of the control system, electromagnetic shielding,filter and grounding are analyzed. Relevant measures are put in to practice too. These measures prove that the experiments on re-straining EMI of high- power electromagnetic environment are effective and feasible. The design of control system satisfies the re-quirements of HPM source. Meanwhile, technical support is provided for protection on instruments and equipments in high- power electromagnetic environments.
