Zero-Crossing Time Lower Bounds for the Homogeneous Super-Twisting Algorithm
Diego Gutiérrez-Oribio, Ioannis Stefanou
High-frequency switching and chattering are well-known problems in sliding-mode control. Although the super-twisting algorithm produces a continuous control input, the sliding vari…
Modular Sign Compensation for MIMO Systems with Unknown Control Direction: An Exact Nominal Recovery Approach
Diego Gutiérrez-Oribio, Ioannis Stefanou
This paper addresses stabilization of MIMO systems with uncertain time-varying diagonal input direction. We propose a modular switching sign-compensation layer acting as an outer w…
A Control Framework for Induced Seismicity Mitigation in Groningen Gas Reservoir
Diego Gutiérrez-Oribio, Ioannis Stefanou
Induced seismicity associated with gas production poses major operational and societal challenges, as illustrated by the Groningen field in the Netherlands. While many studies have…
A shifted interface approach for internal discontinuities in poroelastic media
David Michael Riley, Guglielmo Scovazzi, Ioannis Stefanou
Porous media containing cracks, fractures, or internal discontinuities arise throughout subsurface geomechanics, biomechanics, and materials science. Numerical simulation of the co…
Slip, Differentiate, Observe: State and Parameter Estimation for Rate and State Friction from Noisy Data
David Michael Riley, Diego Gutiérrez-Oribio, Ioannis Stefanou
Quantifying frictional properties of interfaces remains a major challenge in both terrestrial and extraterrestrial geomechanics, where available samples, laboratory apparatuses, an…
Reinforcement learning-based adaptive time-integration for nonsmooth dynamics
David Michael Riley, Alexandros Stathas, Diego Gutiérrez-Oribio +1
Numerical time integration is fundamental to the simulation of initial and boundary value problems. Traditionally, time integration schemes require adaptive time-stepping to ensure…
Control of Human-Induced Seismicity in Underground Reservoirs Governed by a Nonlinear 3D PDE-ODE System
Diego Gutiérrez-Oribio, Ioannis Stefanou
Induced seismicity caused by fluid extraction or injection in underground reservoirs is a major challenge for safe energy production and storage. This paper presents a robust outpu…
AI-Driven approach for sustainable extraction of earth's subsurface renewable energy while minimizing seismic activity
Diego Gutierrez-Oribio, Alexandros Stathas, Ioannis Stefanou
Deep Geothermal Energy, Carbon Capture and Storage, and Hydrogen Storage hold considerable promise for meeting the energy sector's large-scale requirements and reducing CO emis…
Insights of using Control Theory for minimizing Induced Seismicity in Underground Reservoirs
Diego Gutierrez-Oribio, Ioannis Stefanou
Deep Geothermal Energy, Carbon Capture, and Storage and Hydrogen Storage have significant potential to meet the large-scale needs of the energy sector and reduce the CO emissio…
