核反应堆功率模糊动态矩阵控制

Fuzzy dynamic matrix control of nuclear reactor power

为了提高核电机组功率控制器的负荷跟踪性能,基于T-S模糊模型,针对点堆中子动力学方程设计了模糊动态矩阵控制器.利用改进型的动态矩阵控制算法在工作点附近设计局部控制器.在强非线性的全局控制范围内,利用并行分布补偿(PDC)方法,将各工作点处的局部控制器统一起来,从而扩大了反应堆功率控制中动态矩阵控制器的适用范围.计算机仿真结果表明,对于所选取的3种典型的运行工况,所设计的控制器都能在保证安全的前提下,在全局范围内表现出良好的负荷跟随能力.

In order to improve the load -following capability of nuclear reactor power control-ler, global fuzzy dynamic matrix controller which is based on T -S fuzzy model , was de-signed for point reactor neutron kinetics equations .Firstly, using the modified dynamic ma-trix algorithm, local dynamic matrix controllers were designed in the vicinity of the working points.Secondly, local controllers were unified in the global and strong nonlinear range by using the parallel distributed compensation （ PDC） method.It expanded the scope of appli-cation of the dynamic matrix controller in nuclear reactor power control .The simulation showed that the controller had a good global load -following capability in the three typical operating conditions and it could also ensure the safety of nuclear reactor .
