一种改进的基于再励学习算法的模糊神经BOXES控制系统

本文给出了一种改进的基于再励算法的神经网络ＢＯＸＥＳ控制系统,引入超维椭球体模糊划分状态空间的概念,并且通过神经网络的再励学习邮对状态空间的自动划分。最后,应用到倒立摆控制中的仿真结果展示了控制系统的有效性。     

A Novel Catalytic System—NdCl_3·HMPA/Al(i-Bu)_3 for Copolymerization of Isoprene and Styrene

Introduction Rare-earth coordination catalysts are known for their high activity and high stereospecificity in the polymerization of conjugated dienes.1-5 The copolymerization of styrene (St) with butadiene using rare earth catalyst was followed with interest soon as the rare earth coordination catalyst appeared in the early 1960s.6-14 Copolymerization of isoprene (IP) and St using coordination catalysts was reported in a few papers,10,15-18 among them only Jin et al.10 and our group18 repor…
