摘要

提出了一种适用于自修复飞控系统的故障检测与隔离技术。FDI采用单纯形优化程序在线估计受战斗损伤影响的系统参数，从而为实现变结构控制器提供基础，以增加由于表面损伤而产生的地面命令。此外，建议的FDI向正向先导警报(PPA)系统提供故障信息。计算机仿真验证了该方法的有效性，结果表明FDI和SRFCS可以显著改善受损系统的特性

Parameter estimation in a failure detection system of a fighter aircraft

This paper presents a failure detection and isolation (FDI) technique suitable for implementation in a self-repairing flight control system (SRFCS). The FDI employs simplex optimization procedure for on-line estimation of the system parameters affected by battle damage, thus providing the basis for the implementation of a variable-structure controller to augment surface commands due to surface impairments. In addition, the suggested FDI provides failure information to a positive pilot alert (PPA) system. The approach was verified by computer simulations which showed that characteristics of an impaired system can be dramatically improved by FDI and SRFCS.<>
