1Fe_3O_4@MCM-48–SO_3H:合成苯并[f]色烯并[2,3-d]嘧啶酮的高效、可磁性分离纳米催化剂(英文)显示文摘Sulfonic acid groups were grafted onto three different types of synthesized magnetic nanoparticles, namely Fe3O4, Fe3O4@SiO2, and Fe3O4@MCM-48. The sulfonic acid-functionalized nanoparticles were evaluated as catalysts for the synthesis of 5-aryl-1H-benzo[f]chromeno[2,3-d]pyrimidine-2,4(3H,5H)-dione derivatives in terms of activity and recyclability. Their catalytic activities were compared with that of the homogeneous acid catalyst 1-methylimidazolium hydrogen sulfate([HMIm][HSO4]). The activity of Fe3O4@MCM-48–SO3H was comparable to those of the other heter-ogeneous and homogeneous catalysts.Hassan Kefayati Mostafa Golshekan Shahab Shariati Mahsa Bagheri 2015催化学报2015,36,4:1
2Adaptive Control of a Two-Link Robot Using Batch Least-Square Identifier显示文摘We design a regulation-triggered adaptive controller for robot manipulators to efficiently estimate unknown parameters and to achieve asymptotic stability in the presence of coupled uncertainties.Robot manipulators are widely used in telemanipulation systems where they are subject to model and environmental uncertainties.Using conventional control algorithms on such systems can cause not only poor control performance,but also expensive computational costs and catastrophic instabilities.Therefore,system uncertainties need to be estimated through designing a computationally efficient adaptive control law.We focus on robot manipulators as an example of a highly nonlinear system.As a case study,a 2-DOF manipulator subject to four parametric uncertainties is investigated.First,the dynamic equations of the manipulator are derived,and the corresponding regressor matrix is constructed for the unknown parameters.For a general nonlinear system,a theorem is presented to guarantee the asymptotic stability of the system and the convergence of parameters'estimations.Finally,simulation results are discussed for a two-link manipulator,and the performance of the proposed scheme is thoroughly evaluated.Mostafa Bagheri Iasson Karafyllis Peiman Naseradinmousavi Miroslav Krstić 2021IEEE/CAA Journal of Automatica Sinica2021,8,1:0
