Abstract
AbstractThis paper proposes a sequential test for fault detection in the case of Laplace distribution of residual. This approach is adapted from Wald's sequential test and the paper establishes specific test thresholds for Laplace distributions. The suggested algorithm is applied to the detection of oscillatory failure cases on an Airbus A380 elevator actuator characterized by Laplacian distribution of residual. Moreover the proposed application shows that computing workload resulting from the proposed sequential test is similar to the classical Wald test.
