摘要
The generalized likelihood ratio (GLR) technique performs statistical tests on the innovations sequence of a Kalman filter state estimator. Using the results of these tests, sensor or actuator failures are detected and identified. In this paper, we generalize this strategy for linear dynamic stochastic systems with unknown inputs.
