Integrated Multiple Model-Based H∞ Loop-Shaping Control

Abstract

H loop-shaping control is an excellent strategy, in which control performance and closed-loop stability can be both guaranteed. To use the H loop-shaping control in the multiple model framework to develop a multiple model-based H loop-shaping control method, in which local linear model selection and local controller design are integrated in the multiple model dividing procedure. Therefore, local model redundancy can be avoided and controller structure can be simplified. Besides, desired local control performance and stability are guaranteed by shaping functions. A TITO process is studied. Closed-loop simulation demonstrates the effectiveness of the proposed multiple model-based H loop-shaping method.
