Abstract: This paper improves the hidden nodes pruning strategies of MRAN. The improved MRAN has more compact structure than MRAN. Combining the improved MRAN with IMC, an internal model adaptive control based on improved MRAN is presented, and applied to control the superheated steam temperature of a power station boiler. Simulation results show the presented algorithm has better performances than the conventional control algorithm.

摘要： 通过对最小资源分配网络的隐节点剪裁策略进行改进，使改进的网络具有更加紧凑的结构；通过把改进的最小资源分配网络和内模控制相结合，提出基于改进最小资源分配网络的内模自适应控制，并应用到对电站锅炉过热汽温的控制上。仿真结果表明提出的控制算法与常规的控制算法相比具有更好的控制品质。
