Abstract


With the rapid development of space optical communication , in which an important role in for fine tracking technology in this paper to design and develop a digital servo DSP-based variable structure control method . In order to achieve the fine tracking servo system , real-time and light miniaturization using TI's TMS320F2811 as the core controller text discussion and analysis of the composition and characteristics of the fine tracking servo unit , fine tracking system optimized design , through simulation , too the actual effect of the fine tracking servo system control compensation function , fine tracking system using DSP devices as the main control unit , and experimental verification system . DSP-based embedded fine tracking servo system to achieve a light fine tracking servo system miniaturization . The amount of data per second of the image processing unit 3000 , the digital processing can be exactly in the case of dropped frames completed, the system can meet the requirements of real-time processing . Fine tracking system bandwidth is 300Hz, the accuracy 3urad, reached the predetermined indicators .
