Synthesis of a Stable Discrete-Time Repetitive Controller for MIMO Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents some new results on synthesis and stability analysis of a class of repetitive controllers for discrete-time multi-input multi-output (MIMO) linear time-invariant (LTI) systems. ...
A Comparative Study and Analysis of Semi-Active Vibration-Control Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Semi-active (SA) vibration-control systems are those which otherwise passively generated damping or spring forces are modulated according to a parameter tuning policy with only a small amount of ...
Accelerated Bridge Construction of the New Samuel De Champlain Bridge
Publisher: ASCE
Abstract: Located over the St. Lawrence Seaway, the new Samuel De Champlain Bridge was designed and constructed in 48 months despite the severe winter of Montreal. Many factors, including a deteriorating existing bridge, limited ...
Freeze–Thaw Resistance of Nonproprietary Ultrahigh-Performance Concrete
Publisher: ASCE
Abstract: In cold regions, early deterioration of concretes due to freezing and thawing is a major concern. This study determined the freezing and thawing resistance of ultrahigh-performance concretes (UHPCs) made with different ...
Modeling the Viscosity Behavior of Crumb Rubber–Modified Binder Using Response Surface Methodology
Publisher: ASCE
Abstract: Crumb rubber is one of the waste materials used to improve the behavior of binders. The use of this recycled rubber as a common cheap additive can also help in preserving the environment. Modifying the binder with this ...
Design and Development of a Compact High-Torque Robotic Actuator for Space Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Space robots require compact joint drive systems (JDSs), typically comprising of actuator, transmission, joint elements that can deliver high torques through stiff mechanical ports. Today's conventional space drive systems ...
On Optimum Design of Vibration Absorbers
Publisher: The American Society of Mechanical Engineers (ASME)
A Parametric Study of Bipolar Plate Structural Parameters on the Performance of Proton Exchange Membrane Fuel Cell
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this research, the impact of structural parameters of bipolar plates on the proton exchange membrane (PEM) fuel cell performance has been investigated using numerical method, and this model ...
Theory and Implementation of a Repetitive Robot Controller With Cartesian Trajectory Description
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a new repetitive learning controller for motion control of mechanical manipulators undergoing periodic tasks defined in Cartesian space. The controller does not require knowledge ...
A Polynomial-Based Linear Mapping Strategy for Feedforward Compensation of Hysteresis in Piezoelectric Actuators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A set of memory-based properties is employed in this paper for modeling multiple-path hysteresis response of piezoelectric actuators. These properties, namely, targeting turning points, curve ...
