Direct optimal control for time-delay systems via a lifted multiple shooting algorithm
Journal of Industrial and Management Optimization, 2022 <p style='text-indent:20px;'>Aiming at efficient solution of optimal control problems for continuous nonlinear time-delay systems, a multiple shooting algorithm with a lifted continuous Runge-Kutta integrator is proposed. This integrator is in implicit form to remove the restriction of smaller integration step sizes compared with delays.

Mathematical Modelling, Simulation, and Optimal Control of the 2014 Ebola Outbreak in West Africa
Discrete Dynamics in Nature and Society, 2015 The Ebola virus is currently one of the most virulent pathogens for humans. The latest major outbreak occurred in Guinea, Sierra Leone, and Liberia in 2014. With the aim of understanding the spread of infection in the affected countries, it is crucial to

A Crane Overload Protection Controller for Blade Lifting Operation Based on Model Predictive Control
Energies, 2018 Lifting is a frequently used offshore operation. In this paper, a nonlinear model predictive control (NMPC) scheme is proposed to overcome the sudden peak tension and snap loads in the lifting wires caused by lifting speed changes in a wind turbine blade

Fast Direct Multiple Shooting Algorithms for Optimal Robot Control [PDF]
, 2007 In this overview paper, we first survey numerical approaches to solve nonlinear optimal control problems, and second, we present our most recent algorithmic developments for real-time optimization in nonlinear model predictive control. In the survey part, we discuss three direct optimal control approaches in detail: (i) single shooting, (ii) collocation,

Global Optimal Control Using Direct Multiple Shooting [PDF]
, 2015 The goal of this thesis is the development of a novel and efficient algorithm to determine the global optimum of an optimal control problem. In contrast to previous methods, the approach presented here is based on the direct multiple shooting method for discretizing the optimal control problem, which results in a significant increase of efficiency.

FEBS Letters, EarlyView.The mycobacterial CIII‐CIV respiratory supercomplex is an obligate assembly, encompassing several subunits of unknown functions. We have characterized the intracellular subunit AscF, and show that it is unlikely to be a sensor for metals or nucleotides, but is required for growth on nonfermentable energy sources, and likely works as an adapter for ...
