Fault detection in systems with 2nd order dynamics using transient analysis
J.V. Calvano, Vladimir Castro Alves, Marcelo Soares Lubaszewski · 2003
This work proposes a transient analysis method for fault detection in systems with 2nd Order dynamics using a functional fault model. The approach considers the system pole-zero configuration as its main characteristic and its correspondence with the peak time and the system overshoot is used in order to detect the faults. The input stimulus is a compact test vector which consists of a step, ramp or parabola. The results show that for this sort of circuit 100% of faults can be detected.
