摘要:

介绍了以步进电机为执行元件的跟踪雷达伺服系统。该系统利用数字信号处理芯片精确控制系统的二维运动速度,可以在稳定安全的开环控制情况下实现较高的运动目标追随闭环控制精度。由于此跟踪雷达伺服系统实现数字化的控制,可以根据角度定向灵敏度性能,将目标跟踪经验公式和模糊控制原理方便的结合起来,达到系统带宽和跟踪精度的最佳状态。

关键词: 雷达跟踪伺服控制    
Abstract:

The servo system is one of the most important parts in the tracking radar system. It moves the radar beam to minimize the pointing error between the axial direction of radar beam and the object being tracked. A modern adaptive bandwidth digital control servo system of the tracking radar based on stepper motor is presented in this paper. The servo system controls the movement of the radar system in Cartesian system precisely by digital signal processor, which ensures that the radar system can get high closed-loop control accuracy of target tracking by its safe and steady open-loop control. By using digital control of the system, the empirical formula of target tracking and principle of fuzzy control can be combined to harmonize the system bandwidth and tracking accuracy and make the system run in optimal state, according to performance of angular orientation sensitivity. The servo system of tracking radar based on stepper motor is simpler and more reliable in contrast with the one based on alternating current motor or dc motor. It can find application in the mini-system which does not ask for the capacity for high speed tracking.

Key words: Radar tracking    Digital servo system
