THE FEEDBACK DELAY IN DIGITAL CONTROL

It is a fact that the feedback delay actually ariese in digital control systems.It is necessary to modify the structure of digital control systems and develop new control algorithms,which is done in this paper.A great number of digital computer simulation experiments have shown the obvious advantage of the new algorithms.     

L-色氨酸与α/β-环糊精结合机理的计算研究

本研究通过分子动力学模拟详细探讨α/β-环糊精(α/β-CD)与L-色氨酸(L-Trp)在水溶液环境下的相互作用.通过利用MM/PBSA方法计算结合自由能,表明α/β-CD在水溶液中能够自发的与L-Trp络合,并且β-CD与L-Trp结合能力更强.通过观察α/β-CD与L-Trp的动态结合过程,并计算氢键数量,CD空腔...
