本文提出了一种基于定量反馈理论（QFT）的核反应堆鲁棒功率控制系统。考虑了核反应堆在不同工况下的非线性不确定动态系统。为了设计核反应堆的鲁棒控制系统，识别了两种不同的控制定向线性模型。系统的非线性和不确定性被建模为标称LTI系统的不确定性。QFT控制器的设计和仿真控制反应堆的功率。所提出的控制系统具有良好的性能，在反应堆的操作条件范围广，可以很容易地实现。
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.
