The H_∞ Robust Control of Global Supply Chain System Based on Demand and Time Uncertainty

Abstract:

The H robust control problem of linear uncertain system is studied in this article. With international business has expanded largely in all areas of the world, some problems have also appeared in the global supply chain system. The causes of these problems are mostly from the demand and time uncertainties, so we set up a dynamic cooperation system model to reflect these uncertainties. In a further way, we propose the H robust control strategy and LMI algorithm to reduce the uncertainty influences. And using of SIMILINK tool to make simulation analysis of the system is shown at the end of this paper. Through the setback control of inventory state to restrain the disturbance of uncertain factors, we can achieve an ideal state of global supply chain system in the long run.
