Abstract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.
Other AbstractThe servo system is one of the mo st impo rtan t part s in the t rack ing radar system. It moves the radar beam to m in im ize the po inting error between the ax ial direct ion of radar beam and the ob ject being t racked. A modern adap t ive bandw idth digital control servo system of the t rack ing radar based on stepper mo to r is p resen ted in th is paper. The servo system con t ro ls the movement of the radar system in Cartesian system p recisely by digital signal processor,which ensures that the radar system can get h igh clo sed-loop control accu racy of target track ing by it s safe and steady open-loop con trol.By u sing digital con t ro l of the system , the emp irical fo rmu la of target track ing and p rincip le of fuzzy control can be comb ined to harmon ize the system bandw idth and tracking accu racy and make the system run in op t imal state, acco rding to perfo rmance of angu lar o rien tat ion sen sit ivity. The servo system of t rack ing radar based on stepper mo to r is simpler and mo re reliab le in con t rast w ith the one based on alternat ing cu rren tmo to r o r dcmo to r. It can find application in the m in i2system w h ich does no t ask fo r the capacity fo r h igh speed t rack ing.
