Design of Robust Controller for the Steam Generator in the Nuclear Power Plant Using Intelligent Digital Redesign

지능형 디지털 재설계 기법을 이용한 원자력 발전소 증기발생기의 강인 제어기 설계

This paper describes fuzzy control methodologies of the steam generator which have nonlinear characteristics in the nuclear power plant. Actually, the steam generator part of the power generator has a problem to control water level because it has complex components and nonlinear characteristics. In order to control nonlinear terms of the model, Takagj-Sugeno (75) fuzzy system is used to design a controller. In designing procedure, intelligent digital redesign method is used to control the nonlinear system. This digital controller keeps the performance of the analog controller. Simulation examples are included for ensuring the proposed control method.
