本文研宄非最小相位系统的精确跟踪问题.理想情况下,非最小相位系统针对参考轨迹的精确跟踪可以通过非因果稳定逆方法实现,但控制输入需从负无穷处开始作用.而在实际情况下应用非因果稳定逆算法时,控制输入通过延拓提前作用的时间是有限的,只能得到近似的跟踪效果.本文提出了一种基于最优状态转移的非因果稳定逆算法,能够在实际情况下实现非最小相位系统对参考轨迹的精确跟踪,放松了稳定逆方法对系统的初始状态和延拓时间的限制,而且在相同跟踪效果的条件下,比近似稳定逆方法的延拓时间更短.对比仿真结果验证了所提方法的性能.

过期药对金属缓蚀作用的研究为其回收再利用提供了一个较好的方向,具有一定的环境保护意义。通过失重法、电化学法、形貌分析等方法研究了2种酰胺醇类抗生素过期药在20%醋酸中对A3钢的缓蚀和机理。结果表明:2种药物都是随着浓度的增加缓蚀率提高,并且氯霉素比甲砜霉素缓蚀效果好。动电位极化曲线表明氯霉素和甲砜霉素均属于混合型缓蚀剂,当浓度达到2.0×10^(-4)mol/L时,其对A3钢的缓蚀效率分别为57.0%和55.3%。这2种缓蚀剂的吸附行为均是单分子层物理吸附。

In inverted perovskite solar cells (PSCs),effective modification of the interface between the metalcathode and electron transport layer (ETL) is crucial forachieving high performance and stability. Herein, sulfonatedbathocuproine, commonly known as disodium bathocuproinedisulfonate (BCDS), was employed as a cathode buffer layerto address the interfacial issues at the [6,6]-phenyl-C61-butyricacid methyl ester (PCBM)/Ag interface. BCDS possesses theability to form coordinate bonds with Ag electrodes. Theutilization of the BCDS buffer layer enhanced the chargeextraction capability at the cathode interface whilesimultaneously achieving interfacial defect passivation,improving interfacial contact and increasing the built-in electricfield. Consequently, a power conversion efficiency (PCE) of25.06% was achieved. Furthermore, owing to the excellent filmforminguniformity of BCDS on PCBM, the stability of thedevice was also improved. After storage in dry air for morethan 2000 h, the device maintained 96% of its initial efficiency. This work underscores the remarkable potential of tailoringcoordination groups to enhance charge extraction efficiency at the ETL-cathode interface, unveiling a promising newfrontier in buffer layer development and performance optimization strategies for PSCs.
