This paper originates from a space pre-research project named Ka antenna servo system. In the paper, the writer formulates dual degrees antenna servo system based on Micro-Computer control, and studies the operating principle, design technology, and project problem of the dual degrees antenna servo system.In the paper, after analyzing the gross structure scheme of the antenna servo system, it is introduced how to design the digital control circuit and the control program. The system adopts 80C31 MCU as the main controller, hybrid Rare-Earth permanent magnet stepper motor as the execution component, bio-passage rotary transformer as antenna position sensor. The system runs stably with a high control precision because of appropriate control strategy and meets the desired system value of high precision, low dissipation, multi-function switching. It establishes the foundation of the research about satellites communication antenna servo system.In the research of relative projects, the simplified incremental PID algorithm is discussed , and it is well applied to the relative projects.
Keywords/Search Tags:high precision, low power dissipation, incremental PID algorithm, hybrid Rare-Earth permanent magnet stepper motor, multi-function switching
