| Summary: | 碩士 === 長庚大學 === 化工與材料工程研究所 === 94 === The "Tennessee Eastman Process" was provided by Downs and Vogel in 1993. Several researchers have utilized this TE process to evaluate plantwide process control approaches. There are six operating modes in the TE process. How to operate the mode from one to another was discussed in the MPC control systems, but it was never discussed in the multiple single-inupt-single-ouput control loops. The purpose of this study is to treat the mode transition control in the multiple single-inupt-single-ouput control loops.
Most of the chemical processes belong to multivariate systems. Although using PID with RGA pairing and the decoupler can handle these problems, the control results are not good enough, and the tuning algorithms often depend on operators’ experience. In this direction, this study will modify the proposed mode transition control system by applying other researchers’ design concepts to bring up a new plantwide control structure. The simulation results show that the new plantwide control structure can get better control performance.
