Modeling geologic storage of carbon dioxide: Comparison of non-hysteretic and hysteretic characteristic curves

Earthquake triggering and large-scale geologic storage of carbon dioxide.

Despite its enormous cost, large-scale carbon capture and storage (CCS) is considered a viable strategy for significantly reducing CO(2) emissions associated with coal-based electrical power generation and other industrial sources of CO(2) [Intergovernmental Panel on Climate Change (2005) IPCC Special Report on Carbon Dioxide Capture and Storage. Prepared by Working Group III of the Intergovern...

On the Passivity of Hysteretic Systems with Double Hysteretic Loops

The Bouc-Wen hysteresis model is widely employed to mathematically represent the dynamical behavior of several physical devices, materials and systems such as magnetorheological dampers, lanthanide zirconium or aluminum oxides, mechanical structures or biomedical systems. However, these mathematical models must account for different properties such as the bounded-input bounded-output stability,...

Modeling, Identification, and Control of Hysteretic Systems with Application to Vanadium Dioxide Microactuators

MODELING, IDENTIFICATION, AND CONTROL OF HYSTERETIC SYSTEMS WITH APPLICATION TO VANADIUM DIOXIDEMICROACTUATORS By Jun Zhang Hysteresis nonlinearity in magnetic and smart material systems hinders the realization of their potential in sensors and actuators. The goal of this dissertation is to advance methods for modeling, identification, and control of hysteretic systems. These methods are applie...
