Finite-horizon H∞ Fault Estimation for Linear Time-delay Systems
This paper investigates the finite-time H∞ fault estimation problem for linear time-delay systems,where the delay appears in both state and measurement equations.Firstly the design of finite horizon H∞ fault estimation is converted into a minimum problem of certain quadratic form.Then we introduce an stochastic system in Krein space,a sufficient and necessary condition for the minimum is derived by applying innovation analysis approach and projection theory.Finally a solution to the H∞ fault estimation is obtained by recursively computing a partial difference Riccai equation,which has the same dimension as the original system.Compared with the conventional augmented approach,the solving of an high dimension Riccati equation is avoided.
