摘要

提出了一种分析误差恢复系统对闭环飞行控制系统影响的工具。特别地，本文建立了闭环模型，分析了数字控制系统中误差恢复回滚、复位和冷重启系统的均方稳定性效应。错误恢复机制是由瞬态或间歇性故障触发的，例如由高强度电磁辐射引起的故障。通过对AFTI/F-16飞机纵向动态稳定控制器的分析，说明了该工具的可行性。本例通过确定扰动之间的最小到达间隔来比较不同的恢复方法，从而保持闭环均方稳定性。

Stability analysis of upset recovery methods for electromagnetic interference

Presents a tool to analyze the effect of error recovery systems on closed-loop flight control systems. In particular, the paper develops closed-loop models and analyzes the mean-square stability effect of error recovery rollback, reset, and cold restart systems in digital control systems. The error recovery mechanisms are triggered by transient or intermittent faults which could be caused, for example, by high intensity electromagnetic radiation. The tool is illustrated by analyzing a stabilizing controller for the longitudinal dynamics of the AFTI/F-16 aircraft. This example compares different recovery methodologies by determining the minimum interarrival spacing between upsets which maintains closed-loop mean-square stability.
