The Research And Design Of The Vehicle-mounted "communication In Motion" Servo Control System

With the progress of society and the improvement of information technology,the demand for communication through satellite networks in mobile is becoming more and more important."Communication in moving" as the mobile satellite communication system of fine part is play an important role,in the face of natural disasters and emergencies,the traditional way of communication easily damaged and can not work normally,and "moving" system because of its advantages of flexible,fast response,convenient networking can provide fast communication support.Based on the development of the servo control system of the satellite communication system of vehicle in motion,combined with the past literature,this paper improves the existing vehicle moving through system,and studies,designs and debug the current servo control system.The overall design plan,hardware design and software design of the antenna servo control system are discussed,and the design and implementation of the stabilization and tracking system are introduced in detail.The system selects high performance DSP TMS320F2812 as the main control CPU.It integrates the best features of DSP and micro controller,and has rich chip resources.It has both digital signal processing capability and strong event management ability and embedded control capability.The application of TMS320F2812 to the mobile antenna control system can accelerate the processing speed and make full use of the functional modules on its chip,which can simplify the hardware circuit design and improve the reliability of the system.In the stability and tracking,the application of fuzzy PID control algorithm in the stable system is introduced in detail,and its applicability and correctness are verified by simulation and test.
