[Abstract]:Photoelectric tracking system is widely used in target tracking, video capture and other occasions. The servo control system has an important effect on the speed and accuracy of the photoelectric tracking system. Aiming at the disadvantages of large volume and poor tracking effect of photoelectric tracking servo control system. This paper takes the two-axis optoelectronic tracking system as the research object, and carries on the theory analysis and the system design to the optoelectronic tracking servo control system's scheme design, mathematical model construction, control algorithm, hardware and software design and so on. Firstly, on the basis of understanding the work flow of photoelectric tracking system, the whole scheme of servo control system is determined, and the key components such as driving motor, position detector and other key parts of servo control system are selected. Finally, the control structure is determined to adopt the position, speed and current three-loop control structure, the mathematical model of the photoelectric tracking servo control system is built, and the design method of the "quasi-time optimal" rotational speed and current loop controller is studied and realized. In order to improve the rapidity of servo control system, the PID control algorithm based on TS fuzzy model is studied in view of the high order and nonlinear characteristics of the mathematical model of the controlled object of the position loop controller, and the hardware design is based on the actual engineering. The core control module, position detection module, motor driving current and velocity acquisition module and man-machine interaction module of photoelectric tracking servo system are designed and completed. The software of photoelectric tracking servo control system is studied. The photoelectric tracking servo control system is built and implemented on the simulation platform. The experimental results show that the algorithm has the characteristics of fast response, good stability and strong anti-interference ability. Based on the control structure of servo control system, the compact photoelectric tracking servo control system designed in this paper has certain practical value.
