摘　　要：针对压水堆核电厂冷凝器具有迟延性、复杂非线性等特点,采用集总参数法建立了核电厂冷凝器的动态数学模型,提出了一种基于动态矩阵控制算法的冷凝器压力预测控制方法。在冷凝器压力的非参数模型下,设计动态矩阵控制器,弥补了传统比例-积分-微分(PID)控制方法的局限性。仿真实验结果表明,本文所提出的核电厂冷凝器压力动态矩阵预测控制方法,其响应速度更快、调节时间更短、抗干扰的能力更强,具有良好的控制性能。Aiming at the delay and complex nonlinearity of the condenser of the PWR nuclear power plant,this study uses the lumped parameter method to establish the dynamic mathematical model of the nuclear power plant condenser,and a control method of condenser pressure based on dynamic matrix predictive control algorithm is proposed.Under the non-parametric model of condenser pressure,a dynamic matrix controller is designed to make up for the limitations of traditional PID control methods.Finally,the simulation experiment results show that the proposed dynamic matrix predictive control method for condenser pressure in nuclear power plants has faster response speed,shorter adjustment time,stronger anti-interference ability,and good control performance.
