Abstract

The robust control problem for nonlinear multi-unit chemical processes is addressed. The processes discussed admit a set of plant decompositions in an operating region which corresponds to the variation of the operating point caused by disturbances. A passivity based approach is proposed to design decentralized controllers for these processes, namely, the proposed method determines the best local plant decompositions based on evaluation of a passivity index, and assesses the closed-loop stability and performance using the best local plant decompositions. Local decentralized controllers can be designed based on the best local plant decomposition to achieve the desired closed-loop stability and performance
