Research Of Computer Aided Tracking Technique Of Regenerative Feedback In Servo System

In the servo control system, how to improve the tracking accuracy of the servo system, has always been a core issue to be resolved by the servo control system. In order to reduce the tracking accuracy, the servo system has gone through the open-loop control, closed-loop control, open the closed-loop composite control and computer control stage. This article focuses on a method of the use of modern computer-aided tracking technology to improve the tracking accuracy. Based on an optic-tracking-devise of Navy, the disquisitions study this modern computer-aided control technology, high-precision tracking technology to achieve the goal of high-speed target. In the process of automatic target tracking, try to obtain the velocity and acceleration of the target in the geodetic coordinate system, after coordinate transformation introduced into the servo system input terminal, If we can accurately measure the target motion parameters, The system line of sight can be accurately aligned with a moving target, thereby effectively reduce the dynamic hysteresis error of the servo system.
