摘要
飞行控制系统是影响飞机飞行安全的关键系统,为了满足安全可靠性指标要求,一般采用多余度设计。保证多余度系统协调工作是余度系统需要重点关注的问题。当前有2种余度计算机机制,即同步计算机机制和异步计算机机制。文中分析了同步计算机机制和异步计算机机制下的基本架构、工作原理和故障监控等策略,对比了2种机制的优点和缺点,为飞控系统设计提供借鉴。
The flight control system is the key system which affects the flight safety of the airplane.For meeting the requirement of safety reliability index,redundant design is adopted generally.To ensure the coordination of redundancy system is the key problem of redundancy system.Currently,there are two kinds of redundant computer mechanism,namely synchronous mechanism and asynchronous mechanism.This paper analyzes the basic architecture,working principle,fault monitoring and other strategies of synchronous and asynchronous mechanisms.Comparing the advantages and disadvantages of the two architectures,and provides for the flight control and flight manage system design.
