为提高核反应堆运行的负荷跟随能力,设计了基于T-S模糊模型的包含模糊状态观测器的积分控制系统。该方法将非线性的点堆动力学方程在一些选定工况点进行线性化,采用并行分布补偿(PDC )方法,设计模糊积分控制器和模糊状态观测器,以相对于额定功率平衡状态的相对中子密度为前件变量,构造T-S模糊控制系统。引入模糊状态观测器,成功解决了部分状态变量不能测量的困难。使用线性矩阵不等式(LM I)方法进行稳定性分析,保证了此控制系统的大范围稳定性。仿真结果验证了这种控制系统能在大范围运行工况下工作良好。

An integral control system with fuzzy state observer based on Takagi-Sugeno (T-S) fuzzy model was designed in order to improve the load-following capability of nuclear reactor .Linear models were derived from the original nonlinear point reactor kinetics equations on several operating points . The fuzzy integral controller and the fuzzy state observer were designed by using the parallel distributed compensation (PDC) technique ,and the T-S fuzzy control system was constructed with the relative neutron density referenced to the equilibrium condition of rated power as the premise variable . The problem that part of state variables can not be measured was successfully solved by introducing fuzzy state observer .The stability analysis was given by means of linear matrix inequality (LMI) approach ,and the control system was guaranteed to be stable within the large range . The simulation results demonstrate that the control system works well over a wide region of operation .
