An application of robust control technique to manufacturing systems with uncertain processing time

This paper studies the inventory control problem for a production system wi th uncertain processing time and delay in control, First, the stabilization of the delayed system is analysed. Then, a controller is designed such tha t a disturbance attenuation of the system is achieved. The problem of robus t control of the system with parametric uncertainty is also investigated. L inear matrix inequality approach is employed to solve the above problems. A numerical example is given to show the potential of the proposed technique s, Copyright (C) 2000 John Wiley & Sons, Ltd.
