Abstract
We present techniques for residual-generation as the basis for statistical hypothesis testing for fault detection in stochastic systems. If a system model is not available, we perform system identification using an ARMAX or NARMAX structure. We propose that a Kalman filter is used to estimate the ARMAX model, and a feedforward neural network is used to estimate the NARMAX model. The test of hypothesis can be done directly on the residual if the system is single-output. For multi-output systems, we show how a neuron can be used to implement a Chi-squared test.
