在某高功率微波系统中，通过控制多路移相器的位置，来达到对微波波束的精确控制。在伺服控制系统的设计中，为了解决强电磁场对伺服系统的干扰与破坏，在设计时从控制系统方案设计、系统组成、移相器单元设计、位置传感器设计、位置环路设计、电路板设计、机箱设计、传输线缆等方面进行严格的针对性设计与处理。设计过程中，对关键器件与部件进行现场试验进行方案验证与选择。最终，在高功率微波系统对目标进行连续辐射的实测中，工作稳定可靠，控制系统对多路移相器的定位精度达到0.1 mm，达到了预期的效果。

In a high power microwave system, the precise control of the microwave beam is achieved by controlling the position of the multichannel phase shifter. In the design of servo control system, in order to reduce the interference and damage of the strong electromagnetic field to the servo system, the control system conceptual design, phase shifter design, position sensor design, position loop design, circuit board design, chassis design, transmission cable and other aspects are strictly executed and handled. During the design process, field experiments were carried out for the verification and selection of the key components. Consequently, the high-power microwave system is stable and reliable, and the beam control achieves the expected precision (0.1 mm) in a test of continuous radiation on the target.
