研究室紹介
Professor Thomas B. Cho's research lab specializes in advanced control systems for nuclear power plant components, with a primary focus on the robust and intelligent control of nuclear steam generators. The lab develops innovative fuzzy logic-based control strategies, including fuzzy logic controllers, filters, and gain scheduling techniques, that ensure stability and performance under uncertain and varying operating conditions. By integrating modern control theories such as H∞ control and LQR with fuzzy logic, the lab aims to enhance safety, reliability, and efficiency in nuclear energy systems.

4A fuzzy logic controller (FLC) and a fuzzy logic filter (FLF), which have a special type of fuzzifier, inference engine, and defuzzifier, are applied to the water level control of a nuclear steam generator (S/G). It is shown that arbitrary two-input, single-output linear controllers can be adequately expressed by this FLC. A procedure to construct stability-guaranteed FLC rules is proposed. It contains the following steps: 1) the stable sector of linear feedback gains is obtained from the subopt
A robust fuzzy logic gain scheduler (robust FLGS) is designed, based on the synthesis of fuzzy logic inference and the H/sub /spl infin// technique. The robust FLGS has a set of robust control gains in a gain pool. The fuzzy inference engine chooses one of the most desirable control gains considering the steam generator (S/G) operating condition. The robust gains in the gain pool are obtained by the time-domain H/sub /spl infin//-control technique such that both of the weighted H/sub /spl infin/
