Abstract EN
This paper investigates the H∞ fixed-lag fault estimator design for linear discrete time-varying (LDTV) systems with intermittent measurements, which is described by a Bernoulli distributed random variable.
Through constructing a novel partially equivalent dynamic system, the fault estimator design is converted into a deterministic quadratic minimization problem.
By applying the innovation reorganization technique and the projection formula in Krein space, a necessary and sufficient condition is obtained for the existence of the estimator.
The parameter matrices of the estimator are derived by recursively solving two standard Riccati equations.
An illustrative example is provided to show the effectiveness and applicability of the proposed algorithm.
