Modeling and robust LQ regulator designing for refining process

This paper presents a synthetic design procedure for a robust LQ regulator for refining process, including modeling and robust optimal system designing. The paper discusses three major topics: mathematical modeling of the process with large uncertainty, determination of a synthetic performance index for optimizing the process, and design of the robust optimal system with robust guaranteed stability. This research result is a part of preliminary results of the real refining process optimal control system implemented in the Minfeng Paper Mill, Zhejiang Province. Simulation test results showed that the proposed modeling and control algorithm are efficient and practicable.
