"Moving" Antenna Servo Control System Platform Design For Ship

Mobile satellite communications ("Moving") technology has great potential for development and application. Which core technology is the movement of isolated vector pointing antenna interference and ensure stable tracking antenna pointed at the satellite. This paper applies to the sea fishing "Moving" system, mainly to study its tracking and stability control technology, completed the following work:1. The overall design of the system proposed design based on three-axis tracking platform independent, and the main core of the device for selection according to the system design goals and technical indicators.2. It provides a framework for the entire hardware system which designed to control the core STM32F407 hardware circuit, modular design, according to different functions can be divided into:Power module, control core module, motor drive module and signal receiver module. It analyzed separately for each module, component selection and circuit design, and gives the final circuit design.3. The three-axis structure of the system are designed axis system control strategy for roll and pitch control using a feed forward control scheme with a combination of closed-loop feedback, orientation control using closed-loop control strategy.4. Aim to the noise signal gyroscope, using recursive least squares polynomial fitting algorithm and Kalman filtering algorithm for gyro output signal filtering, analysis and comparison, this system will eventually employ recursive least squares polynomial fitting algorithm, and gives the actual filtering processing result.5. Thinking for modular, system software design, including the initial module for satellite tracking modules and stable, given software design methods and software flow chart corresponding modules.6. Antenna stabilization and tracking system software and hardware FBI, through three axial analog swing boats at sea by the disturbance of the dynamic three axial antenna system debugging, testing out of the stable tracking accuracy of the system, the basic realization of the proposed system design specifications.Finally, a summary of the system and the prospect of further research work carried out, I hope the next stage in the performance of the system can be more advantageous.
