Abstract :
Focuses on unconditional stability problems of a class of linear systems described by delay-differential equations with commensurate delays. An algebra test for unconditional stability of such systems is given. The proposed approach makes use of some results of the current study of complete discrimination systems. Based on such a test, an efficient online algorithm is also presented for numerical implementation. Note that delay margins of the system can also be computed in our algorithm when the delay-independent criterion fails
