飞行器执行机构控制型SOC芯片设计

SOC design for spacecraft control actuator

针对目前用于航天飞行器的关键控制器芯片国产化不高、严重依赖进口受制于人的问题,分析航天产品对器件的特殊要求和芯片的功能需求,设计了一款基于SPARC V8内核的卫星执行机构控制器主芯片SOC812A,详细介绍了SOC812A芯片的结构和设计流程,通过搭建直流无刷电机控制系统验证SOC812A芯片的性能,最后通过实际项目验证了此款芯片在航天控制器中的应用情况,应用情况表明,SOC812A芯片大大提高了电子线路的集成化,并且执行机构的控制精度也得到了提升。

At present,the key chip for spacecraft localization is not high localization and heavily dependent on imports.Through analyzing the space environment and functional requirements of the chip,This paper designed SOC chip based on SPARC V8,which is used in satellite control system,first described the architecture and design process of SOC812A,Then validated its application in aerospace control actuator through current project.The application shows that SOC812A greatly improved the integration of electronic circuits and And actuator control accuracy had also been improved.
