J. Cent. South Univ. (2018) 25: 2258-2271 DOI: https://doi.org/10.1007/s11771-018-3911-8 Superposed disturbance mechanism of sequential overlying strata collapse for gob-side entry retaining... of Springer Nature 2018 Abstract: Gob-area roof rupture movement is a key disturbance factor for gob-side entry retaining. The characteristics of gob-area sequential roof collapse of overlying strata......
J. Cent. South Univ. (2017) 24: 2019-2027 DOI: https://doi.org/10.1007/s11771-017-3611-9 Disturbance rejection control for Raymond mill grinding system based on disturbance observer NIU Dan(牛丹... occur. To improve disturbance rejection performance, a control scheme based on PI and disturbance observer is proposed in this work. The scheme combines a feedforward compensation part based......

;文献标志码:A 文章编号:1672-7207(2014)08-2640-08 L2 filtered backstepping control based on nonlinear disturbance observer JIA Heming, SONG Wenlong (College of Mechanical and Electrical Engineering, Northeast Forestry University, Harbin 150040, China) Abstract: A L2 filtered backstepping control method based on the nonlinear disturbance observer for a general......
. The combined effect of static stress and dynamic disturbance causes the damage around the tunnel, and initial stress conditions control the damage morphology. The blast disturbance cannot fundamentally change... on the tunnel by the dynamic disturbance is. The AE activity recovers to a relatively stable state within a short time after the blast and conforms to power-law characteristics. Key words: tunnel damage......
Calculation of Soil Deformation in Area of Disturbance Due to Pipe-jacking Construction SHI Cheng-hua, HUANG Lin-chong (School of Civil and Architectural Engineering, Central South University, Changsha 410075, China) Abstract: As the present calculated formulas of soil deformation in the area of disturbance due to pipe-jacking construction have some defects, a new calculated method was put forward......
