Research On The Optoelectronic Tracking Servo Control System

Optoelectronic tracking system is widely used in target tracking, the video acquisition, etc. For the rapidity and accuracy of the optoelectronic tracking system, the servo control system has important influence. According to the disadvantages of large size and the poor control effect in the optoelectronic tracking servo control system, this paper plans to design the compact optoelectronic tracking servo control system, and to improve the traditional control system. As a two-axis optoelectronic tracking system for study, this paper analyzes and designs the cord control system, the mathematical model, the control algorithm, the hardware and the software design.Firstly, based on the understanding the work flow of optoelectronic tracking system, this paper analyzes and selects the type of the driving motor, the position detection device and other key components in optoelectronic tracking servo control system.. At last, the servo control system uses the position-speed-current control structure. This paper builds the mathematical model of the optoelectronic tracking system. In order to improve the rapidity of the servo control system, the speed-current control algorithm chose the "Near time optimal" method. According to the characteristics of advanced and nonlinear mathematical model, which is the model of the controlled object of position control loop, the position control algorithm chooses the PID control algorithm based on the TS fuzzy model. The servo control system’s hardware system design is based on the actual project, and this paper design and complete the core control module, the position detection module, the motor driving module with current and speed detection and the man-machine interaction module of the optoelectronic tracking servo control system. At last, this paper details the key technologies of the servo control system software.Build and implement the entire optoelectronic tracking servo control system on the simulation platform, the simulation result shows that:the system has fast response, well stability and strong robustness. Base the structure of the servo control system, the compact optoelectronic tracking servo control system, which this paper designed, are same practical value...
