为了提高永磁同步电机伺服系统中的位置控制性能,提出一种基于状态观测器和状态反馈的位置控制器。状态观测器可以利用较低精度的位置传感器来准确观测负载转矩、转子位置和转速。基于状态空间算法的位置控制器通过合适的零极点配置,可以提高位置控制性能。利用观测的负载转矩可以把负载的变化作为系统扰动进行补偿。仿真和实验结果表明:该控制器与传统的比例积分微分控制器相比,位置控制快速准确并且没有超调,在负载变化时系统仍然能够保持很好的稳定性和控制精度。

拉萨地体位于西藏高原的南端,其构造演化对青藏高原的形成具有重要的研究意义。虽然目前已有许多研究成果,但是对于印度-亚洲大陆碰撞之前拉萨地体的构造与古地理演化仍然存在很多未知和争论。为了查明拉萨地体早期构造演化过程,我们选取拉萨地体中部的措勤盆地为研究对象。措勤盆地发育完好的中上白垩统地层,其主要包括澎波组和达雄组。研究区位于措勤县城以北约30k.,达瓦错附近。澎波组沉积不整合于下伏早白垩世则弄群火山岩之上,由一套厚约80m.含圆笠虫灰岩组成。微相分析该组沉积于低能浅海的礁相或泻湖环境中。底栖有孔虫分析表明其形成时代约为Aptian晚期到Cenom.nian早期(13-96 m.)。达雄组为一套巨厚层(700m.,粗砂岩,砾岩及粉砂岩、泥岩构成。其形成于冲积扇和辫状河环境。由下伏澎波组与夹层凝灰岩推测达雄组的形成时间大约为96-92m.之间,反映了达雄组很高的沉积速率(>0.4k. m.r-1)。通过古水流,砂岩岩石学,碎屑锆石U-Pb年代学和Hf同位素分析,达雄组沉积主要来自北部拉萨地体。在晚白垩世时期,拉萨地体北部两条相向的冲断带(Gugu La和Gaize Selin Tso断裂带)发育,将北部拉萨抬升至区域较高的地形条件,其对应沉积环境也由浅海(澎波组)向陆相(达雄组)转变。基于该时期古地理条件的变化,我们认为措勤盆地中晚白垩世达雄组沉积于北部拉萨隆升的构造背景之下,其演化类似于中安第斯Altiplano盆地晚渐新世的Hinterland盆地。由此我们认为措勤盆地达雄组反映了在隆升的北部拉萨地体内,形成的受区域性断裂控制的沉积区,其可能暗示了在印度-亚洲大陆碰撞之前,北部拉萨地体已经开始了早期的隆升。

Back.rounds: Recent advances in post k.dney Transplantation (k.) care, have led to a dram.tic im.rovem.nt in short-term.outcom.s in order to achieve transplantation tolerance;including the ideal tool for clinical m.nitoring & new therapeutic line. This study was undertak.n to analyze the CD62L in k.dney Transplant Recipients (k.Rs) and to investigate its efficacy as a m.rk.r of good graft survival. m.thods: Fifty pediatric k.Rs and 12 healthy controls were included in the study, the frequency of T cell activation m.rk.rs;CD62L was m.asured with flow cytom.try after renal transplantation. Clinical, laboratory, im.unosuppressive therapy data and graft function of transplant recipients were collected and correlated with their CD62L peripheral blood percentage. Results: The circulating CD62L% was significantly m.re in transplant recipients than controls (44.74% ± 17.45% vs. 33.36% ± 11.54%, p = 0.02). CD 62L% was m.re frequent in recipients of living related donors (p = 0.05), positively correlated with donor age (p = 0.04, r = -0.29*) and CD 4% (p = 0.000, r = 0.615). CD26L% did not show significant association with acute rejection or chronic rejection (p = 0.432, p = 0.91 respectively) or with graft function (serum.creatinine or eGFR, p = 0.086, p = 0.988 respectively) or im.unosuppressive m.dications. Conclusion: Peripheral CD62L% is increased after k. than healthy controls, however, it cannot reflect either clinical (serum.creatinine and eGFR) or pathological renal graft injury. CD62L surface m.rk.r needs m.re analysis for its potential diagnostic and therapeutic im.lications as a Treg cell activation m.rk.r.
