Optimal control of differentially flat systems is surprisingly easy

Automatica
As we move to increasingly complex cyber-physical systems (CPS), new approaches are needed to plan efficient state trajectories in real-time. In this paper, we propose an approach to significantly reduce the complexity of solving optimal control problems for a class of CPS with nonlinear dynamics.

Antibiofilm activity of a chionodracine‐derived peptide by NMR‐based metabolomics of cell‐free supernatant of Acinetobacter baumannii clinical strains

FEBS Open Bio, EarlyView.
KHS‐Cnd peptide is able to impair biofilm formation and disaggregate mature biofilms in Acinetobacter baumannii clinical isolates. Differences in extracellular metabolites reflect changes in biofilm metabolism due to KHS‐Cnd treatment. Among the differentially represented extracellular metabolites upon KHS‐Cnd treatment, the significantly altered ...

Accurate Tracking of Agile Trajectories for a Tail-Sitter UAV Under Wind Disturbances Environments

Drones
To achieve more robust and accurate tracking control of high maneuvering trajectories for a tail-sitter fixed-wing unmanned aerial vehicle (UAV) operating within its full envelope in outdoor environments, a novel control approach is proposed.

Assessment of Aerial Combat Game via Optimization-Based Receding Horizon Control

IEEE Access, 2020
This paper focuses on modeling of air-to-air combat via optimization-based control and game-theoretic approach. The flatness property of the dynamical system is used to present aircraft dynamics in terms of specific variables and their derivatives that ...

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Active Control of Laser Wavefronts in Atom Interferometers

, 2017
Wavefront aberrations are identified as a major limitation in quantum sensors. They are today the main contribution in the uncertainty budget of best cold atom interferometers based on two-photon laser beam splitters, and constitute an important limit ...

Differential Flatness Properties and Feedback Control of the Fokker–Planck PDE [PDF]

Intelligent Industrial Systems, 2016
The Fokker–Planck PDE describes the dynamics of several biochemical and biological processes, as well as of phenomena at molecular scale. In this paper, the problem of feedback control of the Fokker–Planck PDE is studied. It is shown that the procedure for numerical solution of Fokker–Planck PDE results into a set of nonlinear ordinary differential ...

Engineering tandem VHHs to target different epitopes to enhance antibody‐dependent cell‐mediated cytotoxicity

FEBS Open Bio, EarlyView.
Tandem VHH targeting distinct EGFR epitopes were engineered into a monovalent bispecific antibody (7D12‐EGA1‐Fc) with more potent ADCC without increasing affinity to EGFR. Structural modeling of 7D12‐EGA1‐Fc showed cross‐linking of separate EGFR domains to enhance CD16a engagement on NK cells.

Active Sensing Control for Differentially Flat Systems

IEEE Control Systems Letters
This paper proposes an optimal active perception strategy using the Constructibility Gramian (CG) as a metric to quantify the richness of the information acquired along the planned trajectory. A critical issue is the dependence of the CG on the transition matrix, whose closed-form expression is not available for most robotic systems while its numerical

A NEURAL NETWORK CONTROL BASED ON DIFFERENTIAL FLATNESS FOR A QUADROTOR [PDF]

Conferência Brasileira de Dinâmica, Controle e Aplicações, 2011
In this paper, a control strategy for a quadrotor using neural network and differential flatness is proposed. Since attitude and altitude of the quadrotor are differential flat outputs for its flight dynamics, neural networks are used to perform the inversion of the flight dynamics and provide the nominal input control for the quadrotor.
