Passivity‐Based Control of Quadratic Boost Converter: An Experimental Case Study

IET Power Electronics
This paper introduces a high‐gain voltage quadratic boost converter (QBC) and for control presents a non‐linear control method based on introduction and damping assignment passivity based control (IDA‐PBC) to regulate it.

Pregabalin contributes to increased recovery time from isoflurane anaesthesia for magnetic resonance imaging in horses. [PDF]

Equine Vet J
Abstract Background Pregabalin reduces excitatory neurotransmitter release and is used for anxiolysis in humans, cats, and horses. The effects of pregabalin on equine recovery following isoflurane anaesthesia are unknown. Objectives To determine if pre‐anaesthetic oral pregabalin influences recovery time and/or quality from isoflurane anaesthesia in ...

Use of Running Equipment Predicts Running-Related Injury in Adult Runners: A Cohort Study of 7347 Runners From the Garmin-RUNSAFE Running Health Study. [PDF]

Transl Sports Med
Background: Running‐related injuries are the most common reason to quit running. There is a gap of knowledge on the use of running equipment as a predictor of running‐related injuries in running populations. Objective: To investigate if runners not using equipment while running have a higher rate of running‐related injuries compared with runners using ...

Solution of matching equations of IDA-PBC by Pfaffian differential equations [PDF]

International Journal of Control, 2021
Finding the general solution of partial differential equations (PDEs) is essential for controller design in newly developed methods. Interconnection and damping assignment passivity based control (IDA-PBC) is one of such methods in which the solution to corresponding PDEs which are called matching equations, is needed to apply it in practice.

Interconnection and damping assignment passivity-based non-linear observer control for efficiency maximization of permanent magnet synchronous motor

Energy Reports, 2022
The permanent magnet synchronous motor (PMSM) has several advantages over the DC motor and is gradually replacing it in the industry. The dynamics of the PMSM are described by non-linear equations; it is sensitive to unknown external disturbances (load),

An IDA-PBC Design with Integral Action for Output Voltage Regulation in an Interleaved Boost Converter for DC Microgrid Applications

Actuators, 2021
This paper describes the output voltage regulation control for an interleaved connected to a direct current (DC) microgrid considering bidirectional current flows. The proposed controller is based on an interconnection and damping passivity-based control

Outcome of Liver Retransplantation in Patients With Primary Sclerosing Cholangitis. [PDF]

Liver Int
ABSTRACT Background and Aims Primary sclerosing cholangitis (PSC) is among the most common indications for liver transplantation in the Nordic countries and with an increasing trend in Europe and North America. Due to post‐transplant complications and high prevalence of disease recurrence this group is at risk of requiring retransplantation (re‐LTX ...

Analysis of instability causes in the bi‐dc converter and enhancing its performance by improving the damping in the IDA‐PBC control

IET Generation, Transmission & Distribution, 2021
The poor damping of bidirectional dc (bi‐dc) converter caused by constant power load makes power system prone to oscillation, and non‐minimum phase characteristic also jeopardises voltage stability.
