RISCalculation of Frequency Response Envelope for Dynamic Systems With Uncertain Parameters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Frequency response finds a wide range of applications in many engineering sectors. When variations and uncertainties exist during the operation and lifetime of an engineering system, the calculation ...
Robust Control Design for Pole Assignment of Uncertain Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This Technical Brief addresses the problem of robust pole assignment for uncertain dynamic systems. A control design methodology is proposed to determine a fixed controller assigning all poles ...
Harmonic Disturbance Observer for Nonlinear Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A nonlinear harmonic disturbance observer for nonlinear systems subject to harmonics is designed and stability of the proposed observer is established using passivity approach. A systematic procedure ...
Statistical Model of a Self-Similar Turbulent Plane Shear Layer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A turbulence probability density function (pdf) equation model is employed to solve a self-similar turbulent plane shear layer. The proper similarity variable was introduced into the problem of ...
Plant Template Generation for Uncertain Plants in Quantitative Feedback Theory
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The creation of templates for uncertain plants is an essential first step in Quantitative Feedback Theory (QFT) and other frequency domain methods. For plants with structured parametric uncertainty ...
A pdf Description of Turbulent Axisymmetric Free Jet Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study presents the applications of a turbulence probability density function (pdf) equation to compute an axisymmetric turbulent free jet flow. In view of the difficulty of solving this ...
Exploration of Relationships between Flood Control Capacity and Peak Flow Reduction in a Multireservoir System Using an Optimization-Clustering-Fitting Framework
Publisher: ASCE
Abstract: Quantifying the relationship between reservoir flood capacity and peak flow reduction can identify reservoirs with good flood control effect and be important for reasonably allocating flood control capacity for larger peak ...
