| 摘 要： | 针对航空发动机动态过程中由于模型误差造成故障检测误报的问题,采用雅克比方法建立航空发动机动态线性变参数(LPV)数学模型反映发动机动态特性,利用特征结构配置法设计故障检测滤波器,较好地消除了模型偏差对故障检测准确率的影响.通过某型涡扇发动机控制系统传感器典型软、硬故障检测仿真实验表明,该方法提高了残差信号对模型误差和未知输入信号的鲁棒性,对发动机加减速过渡过程中故障检测准确度高,实时性好.

| Abstract: | Reducing fault detection mistake in aero engine dynamic process is a hotspot.This paper builds a mathematical model based on LPV modeling to exactly describe the characteristics of aero engine dynamic process,eliminate the effect of modeling error.The FDF is designed using eigenstructure assignment.The simulation results of turbofan engine control systems' typical sensor fault show that this method reduces the difference between residual signal and fault signal,enhances the robustness to unknown input,and t... |
