直流电动机在高精度光电跟踪系统中的应用

The Application of DC Motor to the High Accuracy Photoelectric Tracking System

高精度光电跟踪系统用以完成对模拟动态目标的准确跟踪 ,要求跟踪元件响应快、动态性能好、精度高 ,因此跟踪元件的性能直接影响系统的跟踪特性和精度。直流力矩电机的优点是调速性能好 ,启动转矩大。正是这一特点 ,在高精度光电跟踪系统中尝试使用直流力矩电机控制反射镜跟踪目标。高精度光电跟踪系统要求在一个较大的视场内实现对静态目标和动态目标的高精度快速跟踪。

High precision photoelectric tracking system is applied to the accurate tracking of the analog dynamic targets.It requires the tracking elements to have a fast response speed,good dynamic characteristics and high accuracy,so the characteristics of the tracking elements will directly affect the tracking characteristics and accuracy of the system.The advantages of DC motor is good speed adjustment features and large starting torque.The DC torque motor is tried to be applied to the high accuracy photoelectric tracking system to control the mirror for tracking targets just based on this feature.The high accuracy photoelectric tracking system requires that the high accuracy and fast speed tracking for the static and dynamic targets can be realized within a larger field.
