| 초록 |
We consider a problem of application of analytical redundancy to engine synchronization process of spark ignition engines, which is critical to timing for every ECU process including ignition and injection. The engine synchronization process we consider here is performed using the pulse signal obtained by the revolution of crankshaft trigger wheel (CTW) coupled to crank shaft We propose a discrete-time linear model for the signal, for which we construct FDI (Fault Detcction & Isolation) system consisting residual generator and threshold based on linear observer. {{br}} |
