Frontiers in Energy 2019, Volume 13, Issue 2,   Pages 367-376 doi: 10.1007/s11708-018-0584-9

Abstract: It is difficult to predict the ignition delay times for fuels with the two-stage ignition tendency becausesampling-high dimensional model representation (RS-HDMR) methods were employed to predict the ignition delayA detailed n-heptane chemical mechanism was used to calculate the fuel ignition delay times in the adiabaticBesides, the ignition delay times predicted by both types of correlations were validated against thoseTherefore, it is concluded that HDMR correlations are capable of predicting the ignition delay times

Observer-based control for fractional-order singular systems with order Research Article

Bingxin LI, Xiangfei ZHAO, Xuefeng ZHANG, Xin ZHAO

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 12,   Pages 1862-1870 doi: 10.1631/FITEE.2200294

Abstract: In this paper, for fractional-order with order (0<<1) and is studied. On the basis of the Smith predictor and approximation error, the system with is approximately equivalent to the system without . Furthermore, based on the (LMI) technique, the necessary and sufficient condition of is proposed. Since the condition is a nonstrict LMI, including the equality constraint, it will lead to some trouble when solving problems using toolbox. Thus, the strict LMI-based condition is improved in the paper. Finally, a numerical example and a direct current motor example are given to illustrate the effectiveness of the strict LMI-based condition.
