Influence of the elevation-storage curve in the optimization of hydroplants [PDF]

open access: yesInternational Journal for Simulation and Multidisciplinary Design Optimization, 2009
One of the most important physical characteristics of a reservoir is the elevation-storage curve. In most cases, linear simplification is applied to this curve, which is approximated as a linear relationship.

Pontryagin’s Maximum Principle for the Optimal Control Problems with Multipoint Boundary Conditions

open access: yesAbstract and Applied Analysis, 2015
Optimal control problem with multipoint boundary conditions is considered. Sufficient conditions for the existence and uniqueness of the solution of boundary value problem for every fixed admissible control are obtained. First order increment formula for

A Pareto–Pontryagin Maximum Principle for Optimal Control

open access: yesSymmetry, 2022
In this paper, an attempt to unify two important lines of thought in applied optimization is proposed. We wish to integrate the well-known (dynamic) theory of Pontryagin optimal control with the Pareto optimization (of the static type), involving the maximization/minimization of a non-trivial number of functions or functionals, Pontryagin optimal ...

Sufficient Stochastic Maximum Principle in a Regime-Switching Diffusion Model [PDF]

open access: yes, 2011
We prove a sufficient stochastic maximum principle for the optimal control of a regime-switching diffusion model. We show the connection to dynamic programming and we apply the result to a quadratic loss minimization problem, which can be used to solve a

ON NECESSARY OPTIMALITY CONDITIONS FOR RAMSEY-TYPE PROBLEMS

open access: yesUral Mathematical Journal, 2019
We study an optimal control problem in infinite time, where the integrand does not depend explicitly on the state variable. A special case of such problem is the Ramsey optimal capital accumulation in centralized economy.

The adaptive dynamics of life histories: From fitness-returns to selection gradients and Pontryagin's maximum principle [PDF]

open access: yes, 2012
Using a fitness-returns argument we derive an expression for the selection gradient for the age dependent allocation strategy in a common class of state variable based life-history models.

Optimization of space vehicle combined orbital plane change maneuver on the basis of pontryagin’s maximum principle

open access: yesВестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2019
The task of optimizing the space vehicle combined orbital plane change maneuver with the aim of maximizing its final mass is considered in the paper. Burst of power is used for the vehicle’s exit from the initial low earth orbit and subsequent re-entry ...

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.

Discretization Fractional-Order Biological Model with Optimal Harvesting

open access: yesAbstract and Applied Analysis, 2022
In this paper, a discretization of a three-dimensional fractional-order prey-predator model has been investigated with Holling type III functional response. All its fixed points are determined; also, their local stability is investigated.
