Real‐Time Fractional Control of an Electrohydraulic System Using Low‐Cost Technology

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Advances in control methods for electrohydraulic systems (EHS) improve performance by addressing nonlinearities and unknown parameters, although most studies are limited to numerical simulations. Furthermore, research with experimental validation often relies on high‐performance computing equipment, specialized data acquisition cards, and ...

Dynamic Performance Enhancement of a High‐Agility Hypersonic Mechanical System via a Learning‐Augmented Robust Control Architecture

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The design of control systems for high‐agility mechanical systems operating in extreme environments is a significant challenge in nonlinear dynamics. This paper addresses the complex dynamic control problem of a hypersonic interceptor, modeled as a multi‐input multi‐output (MIMO) mechanical system characterized by strong aerodynamic cross ...

Computational Analysis of the Vibrational Response of Lunar Regolith Made of Nonspherical Grains

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Vibration‐based systems have shown that appropriately oriented and tuned mechanical oscillations can disrupt regolith interlocking and promote flow. Building on this evidence, the present study investigates vibration‐controlled granular discharge as a potential ISRU (In Situ Resource Utilization) strategy, with the aim of supporting ...

Hydro‐Mechanical Modelling of Gas Migration in Bentonite: Formulation and Laboratory‐Scale Validation

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Gas generation and migration in bentonite buffer materials are critical processes affecting the performance of deep geological repositories for radioactive waste. This study presents a new hydro‐mechanical formulation for simulating gas migration in saturated, compacted bentonite, with particular emphasis on the role of non‐uniform stress ...

New and Emerging Artificial Urinary Sphincters for Male Stress Urinary Incontinence: From Gold Standard to Next Generation

Neurourology and Urodynamics, EarlyView.
ABSTRACT Introduction For more than four decades, the AMS‐800 has remained the clinical benchmark device for the treatment of male stress urinary incontinence (SUI). Although it remains the gold standard for male SUI, the AMS‐800 has continued to have limitations such as suboptimal post‐operative continence rates, fixed hydraulic pressure, need for ...
