A Set Point Control for a Two link Underactuated Robot With a Flexible Elbow Joint
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper concerns a setpoint control problem for a twolink underactuated robot moving in the vertical plane with a single actuator at the first joint and a spring between the two links (flexible elbow joint). First, we ...
Discrete Time-Coupled State-Dependent Riccati Equation Control of Nonlinear Mechatronic Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A discrete-time-coupled state-dependent Riccati equation (CSDRE) control strategy is structured in this paper for synthesizing state feedback controllers satisfying the combined nonlinear quadratic regulator (NLQR) and H∞ ...
Very Large Eddy Simulation of Aero-Thermal Performance in Squealer Tip Gap
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To improve the resolution accuracy and get deep insight into the flow structures in squealer tip gap, the very large Eddy simulation (VLES) method was implemented into the commercial computational fluid dynamics (CFD) ...
New Well-Balanced Path-Conservative Numerical Scheme for a Partially Relaxed Two-Layer Hydro-Sediment-Morphodynamic Model
Publisher: ASCE
Abstract: By incorporating horizontal sediment transport and bed erosion into the two-layer depth-averaged shallow water system, one can construct a hydro-sediment-morphodynamic mathematical model in which a variable sediment ...
A Mixed Zero-Equation and One-Equation Turbulence Model in Fluid-Film Thrust Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A thrust bearing is a rotary bearing that facilitates rotational movement between components and is specifically engineered to provide support for a load that is parallel to the axis of rotation. The generation of the ...
Coffee Stain Ring Effect and Nonuniform Material Removal in Chemical Mechanical Polishing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When a drop of coffee dries on the counter-top, it leaves a dense, ringlike stain along its perimeter. Solids immersed in a drying drop will migrate toward the edge of the drop and form a ...
Wave-Mean Flow Interaction and Stratospheric Sudden Warming in an Isentropic Model
Publisher: American Meteorological Society
Abstract: A multilayer isentropic model, with constant potential temperature in each model layer, has been developed to investigate the linear and nonlinear characteristics of motions in the stratosphere. The transition from linear ...
Wavenumber Spectrum of Very Short Wind Waves: An Application of Two-Dimensional Slepian Windows to Spectral Estimation
Publisher: American Meteorological Society
Abstract: A multitaper 2D spectral estimation method is developed for increasing the degree of freedom of the estimation. The core of this method is 2D Slepian eigen windows that are optimum in the sense of minimizing the spectral ...
