Abstract :
This paper is concerned with stability properties of linear time-invariant delay systems. The author considers both retarded and neutral delay systems expressed in state space form. The author´s main goal is to provide a method for computing the maximal delay intervals for which the systems under consideration maintain stability. The author´s results show that this can be accomplished by computing the generalized eigenvalues of certain frequency-dependent matrices. Based on these results, the author also states an improved necessary and sufficient condition concerning stability independent of delay for each of the retarded and neutral systems. The author´s results appear to be simpler and may be implemented more easily than those developed elsewhere.
