Trajectory Tracking Control for a Boost Converter Based on the Differential Flatness Property

IEEE Access, 2019
This paper presents the control design for the regulation and trajectory tracking tasks of the non-minimum phase output voltage of a DC-DC Boost-type power converter. The proposed approach exploits the differential flatness property of the system leading

Safe Learning of Quadrotor Dynamics Using Barrier Certificates

, 2017
To effectively control complex dynamical systems, accurate nonlinear models are typically needed. However, these models are not always known. In this paper, we present a data-driven approach based on Gaussian processes that learns models of quadrotors ...

Pioglitazone plus (−)‐epigallocatechin gallate: a novel approach to enhance osteogenic performance in aged bone marrow mesenchymal stem cells

FEBS Open Bio, EarlyView.
Aged human bmMSCs are seeded in the scaffold. Osteoblastic induction can slightly increase cell's bone‐forming activity to produce bone‐like tissues, shown as the sporadic xylenol orange‐stained spots (the lower left image). Notably, pioglitazone plus EGCG co‐treatment dramatically increases cell's bone‐forming activity and bone‐like tissue production (

ADM Pseudotensors, Conserved Quantities and Covariant Conservation Laws in General Relativity

, 2010
The ADM formalism is reviewed and techniques for decomposing generic components of metric, connection and curvature are obtained. These techniques will turn out to be enough to decompose not only Einstein equations but also covariant conservation laws ...

Flatness based control and tracking control based on nonlinearity measures

IFAC-PapersOnLine, 2017
Abstract This paper deals with the derivation and the simulation of flatness based control and tracking control for a ball in tube system. Flatness based control is a control loop with a two-degree-of-freedom structure in terms of a feedforward (precontrol) and a feedback control path. Tracking control is characterized as a control loop in terms of a

A Comprehensive Overview of the Clinical, Electrophysiological, and Neuroimaging Features of BPAN: Insights From a New Case Series

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Neurodegeneration with brain iron accumulation (NBIA) comprises a genetically and clinically heterogeneous group of rare neurological disorders characterized particularly by iron accumulation in the basal ganglia. To date, 15 genes have been associated with NBIA.

Flatness-based pre-compensation of laser diodes

, 2008
International audienceA physical nonlinear dynamical model of a laser diode is considered. We propose a feed-forward control scheme based on differential flatness for the design of input-current modulations to compensate diode distortions. The goal is to

The Relationship Between Inflammation and Central Nervous System in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Aim Multiple sclerosis is an autoimmune demyelination disease that is seen especially in the young population and has a progressive course, causing motor, sensory, and cognitive deficits. In the literature, the pathogenesis of MS disease and the interconnection between the immune and central nervous system in the disease have not been fully ...
