of switched linear systems under asynchronous switching subject to admissible edge-dependent average dwelltime Research Article

Linlin HOU, Xuan MA, Haibin SUN,houtingting8706@126.com,maxuan24@163.com,fengyun198212@163.com

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 5,   Pages 810-822 doi: 10.1631/FITEE.2000698

Abstract: The problem of stabilizing switched linear systems under is addressed. The method is applied to design a switching signal that comprises slow and fast . Under this switching signal, the restriction that the maximum delay of is known in advance is removed. The constructed Lyapunov function is associated with both the system mode and controller mode. The stabilization criteria and the corresponding algorithm are presented to obtain the controller gains and to design the switching signal. Finally, two examples are given to demonstrate the effectiveness of the proposed results.

Creep-fatigue crack growth behavior in GH4169 superalloy

Dianyin HU, Xiyuan WANG, Jianxing MAO, Rongqiao WANG

Frontiers of Mechanical Engineering 2019, Volume 14, Issue 3,   Pages 369-376 doi: 10.1007/s11465-018-0489-7

Abstract: Crack growth experiments were performed on compact tension specimens using trapezoidal waveform with dwelltime at the maximum load at 650 °C.The crack growth rate of GH4169 superalloy significantly increased with dwell time.The grain boundaries oxidize during the dwell process, thereby inducing an intergranular creep-fatigueIn addition, testing data under the same dwell time showed scattering at the crack growth rate.
