Nonlinear System Fault Detection Based on TLLE

Abstract:

In this work, a nonlinear system fault detection approach based on tangent space distance locally linear embedding (TLLE) is proposed. In the algorithm, tangent space distance is introduced to LLE, which overcomes the shortcoming of original LLE method based on Euclidean distance. It can satisfy the requirement of locally linear much better and so can express the I/O mapping quality better than classical method. Simulation results are given to demonstrate the effectiveness of the fault detection algorithm based on TLLE method.
