Robust Control of the PWR Core Power Using Quantitative Feedback Theory

In this paper, a robust power control system for the nuclear reactor using the Quantitative Feedback Theory method (QFT) is presented. A nonlinear uncertain dynamic system with different working condition has been considered for the nuclear reactor. To design a robust control system for the nuclear reactor, two different controls oriented linear models have been identified. The nonlinearity and uncertainty of the system are modeled as uncertainty for a nominal LTI system. The QFT controller has been designed and simulated to control the reactor power. The proposed control system has a favorable performance over the wide range of reactor operating conditions and can easily be implemented.
