Necessary and Sufficient Conditions For The Stability Of Uncertain Input-Delayed Systems

摘要: Abstract This paper discusses stability analysis supply chain dynamics using feedback control law structure. The case study concerns the inventory system which is considered as an input-delay under uncertainties on customer demands with constraints related to losses of stored products. Due lead time and factors such demand supposed be unknown, objective define a permits satisfy end-customer for production requirements will completely met. end external perturbation. To analysis, two types are proposed, both based predictor necessary sufficient conditions existence then formulated. results demonstrate that it possible improve performances by choosing optimally parameters specifications system.
