RISK-Fold Exosystem and the Robust Nonlinear Servomechanism Problem
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Asymptotic tracking and disturbance rejection in uncertain nonlinear systems is studied in the context of output feedback control. This study is facilitated by formalizing the notion of k-fold ...
On the Robust Regulator for Linear Systems With Limited Parameter Uncertainty
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The linear servomechanism problem has been studied for two extreme cases. On one extreme, the problem has been studied without considering the plant parameter uncertainty. On the other extreme, ...
Optimizing the Feedback Gains of the Robust Linear Regulator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper aims to improve the transient response of a linear regulator system by optimizing the feedback gains associated with a fixed set of desirable eigenvalues of the closed-loop system. ...
Output Regulation for Output Feedback Systems With iISS Inverse Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper develops an approach to dealing with the global robust output regulation problem for a class of nonlinear systems with integral input-to-state stable (iISS) inverse dynamics by using ...
Output Regulation Design for a Class of Nonlinear Systems With an Unknown Control Direction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the solution of the global robust output regulation problem for a class of nonlinear systems without knowing the control direction. The class of the systems is larger than ...
Comparing the Digital Economy Urban Network: Study Based on the Human Resource Needs in the Yangtze River Delta, China
Publisher: ASCE
Abstract: Digital economy has been given a critical mission and momentum to promote high-quality integrated development in the Yangtze River Delta of China. Based on previous research on the spatial distribution of the digital economy ...
Coupled Mechanical and Hydraulic Modeling of Geosynthetic-Reinforced Column-Supported Embankments
Publisher: American Society of Civil Engineers
Abstract: Geosynthetic-reinforced column-supported (GRCS) embankments have increasingly been used in the recent years for accelerated construction. Numerical analyses have been conducted to improve understanding and knowledge of ...
Low-Pressure Polymer Immobilization Methods to Reduce Contaminant Leaching from Deep Vadose Zone Sands
Publisher: American Society of Civil Engineers
Abstract: Water-reactive polymer grouts can be injected directly into contaminated sediment zones where a portion of the contaminated pore water may participate in grout polymerization and contaminants may be immobilized in the grout ...
Coordinated Ramp Metering with Equity Consideration Using Reinforcement Learning
Publisher: American Society of Civil Engineers
Abstract: Reinforcement learning (RL) has been applied to solve ramp-metering problems and attracted increasing attention in recent studies. However, improving traffic efficiency is the main concern of these applications, and the ...
Durability of Polymer Infused Roots Used for Soil Stabilization
Publisher: American Society of Civil Engineers
Abstract: Polymer-infused plant roots can be created without soil excavation by infusing polymer into the roots of plants through the easily accessible above-surface plant stems. Efficacy of this technique for use in soil stabilization ...
