摘 要:为验证飞行控制系统的余度配置方式,设计了多余度飞控系统仿真的软硬件平台。该平台
基于Simulink 图形化的建模方法和Vxworks 嵌入式实时操作系统,利用实时仿真工具(RTW )可
自动生成运行在Vxworks 及相应硬件平台下的代码。还设计了三余度飞控计算机的余度管理算法
和表决算法以验证该平台的功能。本仿真平台的建模方法直观明了,同时可利用Simulink 外部模
式进行实时监控和在线调参,从而提高了平台的升级和维护能力。

Abstract :In order to validate the redundancy allocation scheme of the flight control system, a simulation platform for
multi-redundant flight control system has been designed in this paper. This platform was based on the graphical modeling
method of Simulink and the embedded real-time operating system ——Vxworks, where the executable code could be
compiled for Vxworks and the relative hardware platform by utilizing the real-time simulation tool (RTW). This paper also
proposed the algorithms of triple-redundant management and voting to verify the the functionality of the platform. The
modeling method of the proposed platform was straightforward. Besides, real-time monitoring and online debugging could
be achieved via the external mode of Simulink, leading to the enhancement of the capability of upgrading an
