The Mechanism Study of Alternating Arc(AC)Magnetic Levitation Induction Motor

MATEC Web of Conferences, 2015
Magnetic levitation (no bearings) motor by using magnetic force to make rotor suspend and drive realize its high or ultra-high speed rotating. The stator’s structure of traditional no bearing magnetic levitation motor is double winding which is polar ...

Application to Magnetic Levitation

TEION KOGAKU (Journal of the Cryogenic Society of Japan), 2011
Magnetic levitation systems using HTS bulks, such as magnetic bearing devices for flywheel energy storage systems, transporters, linear actuators, magnetic gears and so on, have been developed by many research groups. Most of the HTS magnetic levitation systems are composed of HTS bulks and permanent magnets.

Robust Position Control of an Electro‐Hydraulic Actuator via Metaheuristic Optimization of a Fractional‐Order PID Controller

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this study, a robust position control strategy is presented for a two‐stage electro‐hydraulic actuator system using a fractional‐order proportional–integral–derivative (FOPID) controller tuned by Kirchhoff's law algorithm (KLA). Electro‐hydraulic systems exhibit strong nonlinearities, parameter uncertainties, and external disturbances ...

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 ...

Variable Structure Control Design for a Magnetic Levitation System

Journal of Engineering, 2018
In this paper the variable structure control theory is utilized to derive a discontinuous controller to the magnetic levitation system. The magnetic levitation system model is considered uncertain, which subjected to the uncertainty in system parameters,

Device‐Induced Blood Damage in Pump‐Assisted Circulation: A Comparative Study of HeartMate III and BrioVAD Pumps

Artificial Organs, EarlyView.
Shear‐induced blood damage—including hemolysis, platelet and neutrophil injury, and von Willebrand factor (vWF) degradation—was evaluated for the BrioVAD and HM3 using an in vitro circulatory loop under clinically relevant conditions. Across 15 biomarkers (n > 6 per group), no significant differences were observed between the two devices.
