中文摘要

      本文论述了工业工程调节控制结构的可行性问题。讨论的问题是，对于某一反馈信息结构，是否存在该结构下的某一分散控制器，以使闭环系统具有渐近稳定性、良好的伺服跟踪性能和鲁棒性。本文基于分散固定模的概念，获得了一般分散控制结构可行性判据。最后将该可行性判据成功地应用于某炼油厂催化裂化装置反应再生系统控制结构的选择及控制系统的设计。结果表明，该分散控制系统具有令人满意的动态性能和鲁棒性。

英文摘要

      The feasibility problem of regulative control structures in industrial processed is addressed in this paper. A control structure being feasible, means there exists a corresponding decentralized robust controller under the structure to make the resulting closed-loop system have asymptotic tracking behavior and asymptotic stability. Using the concept of decentralized fixed modes, we have obtained the feasibility criteria for generally decentralized control structure. Finally, the proposed feasibility criteria have been successfully applied to control structure synthesis for a reactor-regenerator system in fluidized catalytic cracking unit.
