Design And Implementation Of A Certain Type Of Vehicle-borne Optoelectronic Stabilized Tracking Platform’s Control System

In the process of vehicle’s moving, the optoelectronic device that working on it will be impact bythe car’s position. To guarantee the function of optoelectronic device, stable relative to the geographiccoordinate system, it needs a platform that can isolate the vehicle’s moving. In the course of thecampaign, the light wheeled car has large position changes and has a greater position change of theangular velocity and linear velocity, but large car or ship movement is soft and has large inertia. Socar’s stable tracking equipments have higher requirement. This article based on three-axisvehicle-borne stabilized tracking platform as the research objects.First, this paper studies the platform structure, compares the advantages and disadvantages ofdifferent structures, select a three-axis structure programs. In the control system, used integrated servodriver, analyzed and designed of control strategies of communication control panel, according to thecontrol characters of integrated current loop, velocity loop and position loop.For the actual control requirements of the system and the features of platform, in the design of thecontrol algorithm of the communication control board, researched integral separation PID controlstrategy, point out its limitations. And researched the control strategy of fuzzy parameter self-tuningPID, established a system simulation model using MATLAB software, point out the validity andlimitation of fuzzy control in the system of the vehicle platform.Finally, the paper completes the selection of various components of the control system,accomplish the control system which used the servo driver as the core. This article describes thedesignation of communication control panel detailed, finished the design of hardware and ensure itsthrough test, and software design based on the control algorithm analysis. After put the simulation loadon the platform and implement of performance testing, the result show that the control system cansatisfy the requirement of the control indicators.
