- Threshold logic of a decision function is used to evaluate the generated residual so as to enhance the robustness of fault detection systems
- The faults in the automotive engine control systems can be reliably diagnosed by the proposed method through suitable choice of the threshold for the residual signals of the uifdos
- The main contributions of this thesis are shown as follows : firstly , a kind of model based residual generation algorithm , deduced from parity space and aircraft model , is presented to get actuators " and control surfaces " failure signals
- All its properties make it best suitable for the system diagnosis which involves examining 13 analog signals , detecting several digital signal s , issuing the required instructions at an exact pace and sampling many analog signals simultaneously
在硬件设计中选用了pc / 104模块及多功能数据采集模块。实现了加速度计频差信号的动态频率测量、多通道模拟信号的高速同步采样。
- This model is used to generate residual signal by comparing the healthy signal and the signal in the running system . by processing the residual signal , faults from incipient fault to serious fault can be detected effectively
