摘　　要：组建了典型 DDC控制系统的试验模型 ,分别在 2种电磁脉冲模拟器中对其进行了干扰试验 ,测量了不同试验状态下 DDC控制系统受干扰的场强阈值。对系统不同环节的脉冲干扰试验表明 ,DDC通讯线路是引入干扰的主要途径 ,受控设备电源线引入的干扰也会通过其附近 DDC通讯线路对系统形成较强的耦合并导致系统误动作 ,在此基础上讨论了 DDC控制系统的防护措施。A typical direct digital control (DDC) system was established and tested in two electromagnetic pulse (EMP) simulators. The interference thresholds of the DDC system under different test conditions were obtained. It is shown that the major interference path is the communication cable, and the interference introduced by the power line of the controlled equipment can also be coupled to the communication cable and then interfere with the DDC system. The protection approaches are discussed based on these experiment results.
