摘要：
An observer design is proposed for linear systems with time delay. The key of the design is to find a generalized coordinate change such that in the new coordinates all the time-delay terms are injected by the system's output. The existence of such a coordinate change is guaranteed by a rank condition on the observability matrix. Novelty of the proposed design is clearly reflected in the multiple-output case where a dimensional expansion in the coordinate change could become necessary and hence is allowed.
