摘　　要：核电站的动力堆控制系统是一个带不确定参数及干扰的复杂非线性系统 ,采用常规的古典控制很难保证其热功率精确跟踪汽轮机负荷的变化。该文利用系统单位阶跃响应序列建立了一种非参数模型 ,并应用动态矩阵控制原理提出了一种动力堆热功率跟踪负荷变化的数字控制新方法。该方法跟踪调节性能好、鲁棒性强、能消除不可测干扰。通过仿真检验和调试证明了该设计方法的正确性和有效性 。The classical control method is usually hard to ensure the thermal power tracking accuracy,because the nuclear reactor system is a complex nonlinear system with uncertain parameters and disturbances. In the paper, a sort of non-parameter model is constructed with the unit step response of the system. Furthermore, a sort of thermal power tracking digital control law is presented using the dynamic matrix control principle. The control method presented in the paper has good tracking performance and robustness. It can work despite the existence of unmeasurable disturbances. The simulation experiment testifies the correctness and effectiveness of the method. The high accuracy matching between the thermal power and the referenced load is achieved.
