【摘要】 基于小型模块化压水堆的非线性集总参数堆芯模型导出了关于相对功率的"带扰动二阶非线性模型",然后针对导出的模型,提出了一种T-S模糊模型的解析构建方法,包括前提变量的选择、模糊子集划分、隶属度函数结构参数以及模糊后件参数的确定。将所得的T-S模糊模型用于线性自抗扰控制器设计,仿真结果表明,在高、中、低功率水平下均可取得较好的控制效果,证明了所得模糊建模和LADRC设计的有效性,也证明了针对模糊建模设计LADRC比传统的局部线性化设计的LADRC更具优势。更多还原

【Abstract】 Based on the nonlinear set total parameter core model of small modular pressurized water reactor, a ‘second-order nonlinear model with disturbance’ on relative power is derived, and then a method of analyzing and constructing T-S fuzzy model is proposed for the exported model, including the determination of fuzzy antecedent precursors and parameters,the selection of the premise variables, fuzzy subset division, the determination of membership function structure and parameters and fuzzy consequent parameters. The T-S fuzzy model can be used for fuzzy controller design based on linear control system theory, and the simulation results show that good control effect can be obtained at high, medium and low power levels, which proves the effectiveness of fuzzy modeling and LADRC design, and proves that LADRC design for fuzzy modeling is more advantageous than traditional local linearization design更多还原
