摘　　要：内模控制是一种基于过程数学模型进行控制器设计的新型控制策略,具有结构简单、设计直观、无需精确的数学模型、在线调整参数少等优点。为探索内模控制在反应堆控制领域中的应用,以熔盐实验堆堆芯功率控制为例,通过建立熔盐实验堆一回路系统线性化模型,采用内模控制技术,结合粒子群优化算法设计堆芯功率内模控制器。并基于MATLAB/Simulink建立熔盐实验堆一回路仿真系统,开展熔盐实验堆堆芯阶跃反应性扰动下的功率控制研究。结果表明,所设计的堆芯功率内模控制器可很好地控制堆芯功率,实现系统的快速稳定。Internal model control is a new control strategy based on process mathematical model for controller design.It has the advantages of simple structure,intuitive design,no need for accurate mathematical model,and less on-line adjustment parameters.In order to explore the application of internal model control in the field of reactor control,taking the core power control of molten salt experimental reactor as an example,a linearized model of the primary loop system of molten salt experimental reactor was established.The internal model control technology was adopted and the core power internal model controller was designed by combining particle swarm optimization.Based on MATLAB/Simulink,the primary circuit simulation system of molten salt experimental reactor was established,and the power control of liquid molten salt experimental reactor under step reactivity disturbance was studied.The results show that the internal model controller can control the core power well and realize the fast and stable system.
