Design And Implementation Of The Servo Control System Of The Shipborne "Communication In Moving"

The design and implementation of the servo control system of a shipborne "Communication in Moving" are given in this dissertation. The system is mainly used for the fast and reliable communication between ship and satellite, by the "Communication in Moving" technology. Base on Global Position System, single-axis rate gyro, DSP, inertial navigation equipment and single pulse-single channel trace machine, the mixed innovative tracking method, combined the mono-pulse tracking with inertial navigation to track satellite beacon, is adopted in the system.Firstly, the working principle and basic components, used for the shipborne "Communication in Moving" servo control system, is given in this dissertation. And the goal point, mechanical structure and classification of the antenna are discusses, and the key technical requirements and performance indicators are analyzed, then the overall program design of the system is completed. Secondly, the hardware and software design process are given in detail. Stable and track system of the servo control system is established. Major components’choice, installation and performance characteristics are introduced briefly. The control module and drive module of the servo control system are showed in details. Finally, the simulation results and performance analysis show the feasibility and effectiveness of the system.Based on MATLAB language, the dissertation analyzes and simulates the system, to prove that the proposed program is feasible. Finally, it points out the next step of the work according to the problems occurred in the system development process.
