Study Of A Servo System Used In A Mobile Satellite Television Receiver

This paper discusses the process of designing and exploiting the servo system of a kind of mobile satellite television receiver. The purpose of the project is to research and develop a small and economical mobile satellite television receiver equipment system which suits for market demand.Firstly, the paper analyzes the main technical indicators of the mobile satellite TV receiver servo system and completes the overall program design of the system, and the paper analyzes the key technologies and difficulties of the system.The paper introduces the components of the system and calculates the load torque of the system.The components of the system are selected and the performance characteristics of the components are introduced.Secondly, a mathematical model of the servo control system is established, and the traditional PID control and fuzzy-PID control algorithms are designed, and the paper simulates and analyzes the system using MATLAB. The satellite antenna angle is calculated, and the tracking strategies of the servo control system are analyzed. The opened loop and the closed-loop control methods of the system are introduced, and the principle and tracking procedures of the antenna stability system are analyzed.Finally, the hardware platform and functions of the system are introduced, and the software modules and procedures of the system are designed and developed. The paper has a summary of the work and points out the task to be completed in the next step.
