Decentralized control of a multivariable flow-level plant based on robust control approach

Abstract

In this paper a novel approach is proposed to solve a decentralized control problem to stabilize a multivariable system and attenuate the interconnections between its subsystems. To satisfy these conditions, an ut feedback controller is designed by solving an Hinfin control problem. The designed controller is applied to a practical multivariable flow-level plant to show the effectiveness of the proposed methodology. The time delays, transmission zero, two different time constants, and the model uncertainties are the main problems in this plant.
