QuITO: Numerical software for constrained nonlinear optimal control problems
SoftwareX, 2023 We introduce the MATLAB-based software QuITO (Quasi-Interpolation based Trajectory Optimization) to numerically solve a wide class of constrained nonlinear optimal control problems (OCP). The solver is based on the QuITO (the same abbreviation) algorithm,

Optimizing nonlinear adaptive control allocation [PDF]
Modeling, Identification and Control: A Norwegian Research Bulletin, 2005 A control-Lyapunov approach is used to develop an adaptive optimizing control allocation algorithm for over-actuated mechanical systems where the actuator model is affine in the uncertain parameters. Uniform global (asymptotic) stability is guaranteed by the control allocation defined by the dynamic update laws in combination with an exponentially ...

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments
FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

A nonlinear plate control without linearization
Open Mathematics, 2017 In this paper, an optimal vibration control problem for a nonlinear plate is considered. In order to obtain the optimal control function, wellposedness and controllability of the nonlinear system is investigated.

The Optimal Control Problems of Nonlinear Systems
Proceedings of the 12th International Conference on Informatics in Control, Automation and Robotics, 2015 This article discusses the optimal control problem of nonlinear systems, which are described by ordinary differential equations, their right parts are periodic in the angular coordinate. The particularity of the considered in the given work nonlinear control problems is that they take into account the fact that on unfairly long interval of time ...

FEBS Open Bio, EarlyView.In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Optimal Sliding Line Selection for Second-Order Nonlinear Systems
IEEE AccessThis paper focuses on the fundamental problem of sliding line selection in sliding mode control of second-order nonlinear dynamical systems. Although real dynamical systems are rarely accurately described by second-order differential equations, they are ...
