摘要：AbstractThis paper investigates the stability and stabilization of some generic dynamic second-order linear time-invariant system including a single delay in the mathematical representation. As a first result, an appropriate stability criterion based on the manifold defined by the coexistence of the maximal number of negative spectral values is derived. Second, such ideas are exploited in the context of delayed output feedback by an appropriate “partial” pole placement guaranteeing simultaneously the stability in closed-loop and an appropriate exponential decay rate of the corresponding solution for the closed-loop system. To perform such an analysis, the argument principle is explicitly used. An illustrative example completes the presentation.
