Abstract :
The failure detection and correction method recently presented [1,2] for estimating sudden changes in biases that can be measured directly is combined with a method for estimating the bias in a dynamic system using the residuals of a bias-free estimator [3,4] to provide an effective technique for detecting and correcting changes of biases in a linear, dynamic system, The technique is illustrated by a second-order dynamic system with two biases subject to sudden change.
