Fault diagnosis of multiple state-delay systems

摘要：

In this paper,a new fault diagnosis method of multiple state-delay systems is proposed.Firstly,the residual signal is generated by means of a co-prime factorization method.Secondly,a new performance index is proposed by converting the FD problem to a H∞ robust control problem.And then a post-filter is designed as a H∞ robust controller which can make the filtered residual signal close to the fault signal so that the fault estimation purpose can be fulfilled simply.An illustrative design example is used to demonstrate the validity and applicability of the proposed approach at last.
