1Continuous-time System Identification with Nuclear Norm Minimization and GPMF-based Subspace Method显示文摘To improve the accuracy and effectiveness of continuous-time(CT) system identification, this paper introduces a novel method that incorporates the nuclear norm minimization(NNM) with the generalized Poisson moment functional(GPMF)based subspace method. The GPMF algorithm provides a simple linear mapping for subspace identification without the timederivatives of the input and output measurements to avoid amplification of measurement noise, and the NNM is a heuristic convex relaxation of the rank minimization. The Hankel matrix with minimized nuclear norm is used to determine the model order and to avoid the over-parameterization in subspace identification method(SIM). Furthermore, the algorithm to solve the NNM problem in CT case is also deduced with alternating direction methods of multipliers(ADMM). Lastly, two numerical examples are presented to evaluate the performance of the proposed method and to show the advantages of the proposed method over the existing methods.Mingxiang Dai Ying He Xinmin Yang 2016IEEE/CAA Journal of Automatica Sinica2016,3,2:4
2Low-temperature catalytic combustion of trichloroethylene over MnO_(x)-CeO_(2)mixed oxide catalysts显示文摘The cerium-based catalysts were investigated for the catalytic co mbustion of trichlo roethylene(TCE)and exhibit a surprising catalytic activity.MnO_(x)was doped into CeO_(2)by a citric acid(CA)sol-gel method,and the effect of Mn content on the physicochemical properties and catalytic activities of MnO_(x)-CeO_(2)mixed oxides was investigated systemically.The introduction of MnO_(x)into CeO_(2)can evidently improve the catalytic activity and reaction stability of the CeO_(2)catalyst,and the catalytic activity can be maintained for more than 100 h at 250℃under air atmosphere.Moreover,a possible reaction mechanism and a catalytic cycle for the catalytic combustion of TCE over the MnO_(x)-CeO_(2)mixed oxide catalysts are proposed.Kai Shen Mingxiang Jiang Xinwei Yang Weizhong Zhou Qiguang Dai Xingyi Wang Li Wang Yun Guo Yanglong Guo Wangcheng Zhan 2023Journal of Rare Earths2023,41,4:0
