Abstract
A detection observer and residual are designed for a general nonlinear system with polynomial-type nontinearities. A suboptomal approach is also described. The approach is applied to a three-tank hydraulic system for detecting two faults. Three different degree observers, with correponding residuals, are assessed. This observer approach is then compared to the performance of a neural network approach, where the same faults are assessed.
