Advanced control: The augmented SDRE technique

Abstract

This chapter introduces the augmented state-dependent Riccati equation (SDRE) technique for the advanced control of the tandem cold metal rolling process. The advantages of the SDRE method when compared to conventional control are presented. The characteristics of several other advanced control methods are included for evaluation in light of the augmented SDRE method. A brief introductory discussion on linear quadratic control concepts also is included as background in preparation for the presentation of the SDRE technique. The results of simulations using the augmented SDRE method as applied to typical tandem cold rolling applications show the effectiveness of this technique for control of the tandem cold rolling process.
