航空航天控制系统对可靠性和实时性有较高的要求,在新研发的飞行控制软件应用前,需要对其进行地面调试和模拟运行,以验证其是否满足设计要求。本文介绍了一种基于SPARC V8架构的三机冗余仿真系统,内容包括系统的设计方案、主要实现模块和调试验证方法。该系统能够模拟飞行控制系统的硬件部分,从而为飞行控制软件开发人员提供开发调试的硬件环境。 Aerospace control systems have high requirements on reliability and real-time performance. Before the newly developed flight control software is used, it needs to be debugged and simulated on the ground to verify whether it meets the design requirements. This paper introduces a three-machine redundant simulation system based on SPARC V8 architecture, including the design of the system, the main module and debug verification method. This system can simulate the hardware part of the flight control system, so as to provide the flight control software developer with a hardware environment for development and debugging.
