Based On Repetitive Control And Periodic Signal Detection Research On Shipboard Electro-optical Tracking System

Since in the 1960 of the 20th century,electro-optical tracking system gradually become large,medium and small surface ships of the Navy’s Main Search detection,target identification,tracking,target space coordinate measurement equipment.But with the continuous progress of science and technology,rising demand for opto-electronic tracking device use,high precision,high precision tracking,remote probe targets and strong anti-interference ability,is a high-tech Equipment Research of Electro-optical tracker in the world today one of the key issues.This article initially on repetitive control algorithm and periodic signal detection methods,design based on repetitive control and periodic signal detection algorithm of ship-borne optical tracker.The algorithm by building structure functions several times,sample and calculate periodic signals,provide prerequisite for a repeating control.Electro-optical tracking system to achieve without changing the existing equipment structure,improve the existing shake Image stabilization across the accuracy of photoelectric tracker,further reducing regulation time and overshoot,Electro-optical tracker under the surface ship rolling,shake Image stabilization through the index increased to make it smoother tracking,tracking precision of the target further enhanced.Second design based on repetitive control and periodic signal detection algorithm for carrier-based electro-optical tracker,and from the electrical design,software design,structure design and optimization of optical design and other aspects.Most electrical design for hardware circuit,tracking and Optimization Design of power supply system,so as to achieve the elimination of bias,the purpose of tracking the target;Software Design,mainly through embedded in the photo-electric tracking servo control system for the algorithm,improved image stabilization and tracking indicators;Structural Design of main optimized for and display console design of point to improve tracking accuracy of the data;Optical design of the main optimized for optical design and probe design and accomplish the purpose of improving the quality of the image.Finally,after a lot of mathematical modeling,simulation systems measured data and equipment,confirmed based on repetitive control and periodic signal detection algorithm for improving the stability of shipboard electro-optical tracker like the effectiveness of vibration shakes and tracking accuracy.
