A Gain Scheduled Sliding Mode Control Scheme Using Filtering Techniques With Applications to Multilink Robotic Manipulators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a gain scheduled sliding mode control (SMC) scheme is proposed for tracking control tasks of multilink robotic manipulators. In the new scheme, filtering techniques play the key ...
Use of Grouting to Control Horizontal Tunnel Deformation Induced by Adjacent Excavation
Publisher: ASCE
Abstract: A grouting technique is introduced as a measure to protect tunnels adjacent to a large-scale excavation. Field measurements indicated that this grouting technique reduced the maximum horizontal displacement in the tunnel ...
Grouting Theory and Strategy of Simultaneous Control of the Horizontal and Vertical Deformations of Tunnels
Publisher: ASCE
Abstract: Disturbance induced by excavation is a major threat to the structural and operational safety of the tunnel in the vicinity of the excavation. Grouting is considered to be an efficient method for controlling tunnel deformation. ...
Deformation and Protection of Existing Tunnels at an Oblique Intersection Angle to an Excavation
Publisher: ASCE
Abstract: The response of existing tunnels to adjacent excavation at an oblique intersection angle is still unclear. This study investigated the deformation of an existing tunnel when new excavation was conducted obliquely, based ...
Experimental Study on the Applicability of Failure Criteria for Rockfill in Three-Dimensional Stress Conditions
Publisher: ASCE
Abstract: Using local materials to build rockfill dam favors the natural resources, but the strength characteristics of rockfill are quite different for each project, which makes it necessary to explore the applicability of failure ...
