PONTRYAGIN PRINCIPLE AND ENVELOPE THEOREM

open access: yes, 2022
We provide an improvement of the maximum principle of Pontryagin of the Optimal Control problems. We establish differentiability properties of the value function of problems of Optimal Control with assumptions as low as possible.

Using Pontryagin maximum principle for parametrical identification of ship maneuvering mathematical model [PDF]

open access: yesTransport Problems, 2014
This article proposes usage of Pontryagin maximum principle for parametrical identification of mathematical vessel’s model. Proposed method has a special perspective for identification in real time mode, when the parameters identified can be used for ...

Motion planning and control of an installation robot for attitude adjustment of arc parts in underground shield tunneling

open access: yesDeep Underground Science and Engineering, EarlyView.
Inspired by spiders, the multilegged walk‐through assembling robot for arc parts achieves high‐precision synchronous control under heavy loads through dual‐layer hydraulic pose dynamics modeling and hierarchical pressure optimization, significantly enhancing shield tunneling assembly efficiency and precision.

Pontryagin\u27s Maximum Principle for Dynamic Systems on Time Scales

open access: yes, 2017
In this work, an analogue of Pontryagin\u27s maximum principle for dynamic equations on time scales is given, combining the continuous and the discrete Pontryagin maximum principles and extending them to other cases \u27in between\u27.

Investigating Tuberculosis Dynamics Under Various Control Strategies: A Comprehensive Analysis Using Real Statistical Data

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In the present investigation, a mathematical model with vaccination, treatment, and environmental impact under real data is presented. Initially, we present the model without any interventions, followed by an examination of its equilibrium points.

Generalized splines in ℝn and optimal control [PDF]

open access: yes, 2006
We give a new time-dependent definition of spline curves in ℝn, which extends a recent definition of vector-valued splines introduced by Rodrigues and Silva Leite for the time-independent case.

Time‐dependent sensitivity of R0$$ {\boldsymbol{R}}_{\mathbf{0}} $$ and other threshold parameters in seasonal ecological and epidemiological dynamics

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Periodically driven systems are ubiquitous in nature, and their stability against perturbations such as the introduction of a novel pathogens or invasive species is often a major concern. To better understand and control these systems, it is common to assess the sensitivity to changes in the model parameters of stability threshold quantities ...

Optimal Breeding Strategy for Livestock with a Dynamic Price

open access: yesMathematics, 2022
China’s livestock output has been growing, but domestic livestock products such as beef, mutton and pork have been unable to meet domestic consumers’ demands. The imbalance between supply and demand causes unstable livestock prices and affects profits on

Necessary and Sufficient Conditions of Optimality for a Damped Hyperbolic Equation in One-Space Dimension

open access: yesAbstract and Applied Analysis, 2014
The present paper deals with the necessary optimality condition for a class of distributed parameter systems in which the system is modeled in one-space dimension by a hyperbolic partial differential equation subject to the damping and mixed constraints ...
