Design of a linear quadratic gaussian controller for a manufacturing process

Abstract

In this study, the design procedure and the performance analysis of a linear quadratic gaussian controller (LQGC) are presented. The controller is expected to regulate the production–inventory process of a manufacturing system along a pre-determined trajectory within the plant hierarchical control system; the hierarchical control structure is also described briefly in this chapter. The LQGC is based on a dynamic, discrete-time, and a stochastic model, aggregating products, and production processes. The simulation results show that the LQGC is well -suited for the intended purpose.
