摘要
为了确保飞控系统的安全可靠,提出一种基于功能模型的飞控系统安全性设计方法。首先,以需求为牵引,结合飞机的使用场景和性能,实现飞控系统的功能设计;然后,基于安全性设计理念,从系统功能的失效出发实现系统架构的余度设计,同时针对传统方法仅关注系统本身的故障组合分析,存在局限性、滞后性等问题,提出了基于网络化方法开展飞控系统故障推演的功能模型方法;最后,通过应用结果表明了本文所提方法的有效性和可行性。
In order to ensure that the flight control design method of the flight control system based on system of aircraft has high security and reliability, a safety function model is proposed. Firstly, the system function can be designed by means of analyzing the requirement of aircraft, including the performance and using scene of aircraft. Secondly, according to the security theory, the systemic redundancy can be realized based on the func- tion failure. At the same time, a model-based method is proposed to solve the problem of traditional method. Lastly, the application results show the effectiveness and feasibility of the proposed method.
