MATHEMATICAL ASPECTS OF AIRCRAFT ENGINES RUNNING OPTIMIZATION FOR MINIMUM FUEL CONSUMPTION WHILE LANDING

open access: yesНаучный вестник МГТУ ГА, 2017
The consistency of the potential increase of fuel efficiency, based on aircraft maintenance optimization, is mathe- matically proved. The mathematical apparatus and a set mathematical model of aircraft spatial motion allow to analyze aircraft behavior on

Equivalent Models and Exact Linearization by the Optimal Control of Monod Kinetics Models [PDF]

open access: yesBioautomation, 2004
The well-known global biotechnological models are non-linear and nonstationary. In addition the process variables are difficult to measure, the model parameters are time varying, the measurement noise and measurement delay increase the control problems ...

Some Estimates for the Jump of the Derivative of the Lagrange Multiplier Function in Optimal Control Problems with Second-order State Constraints

open access: yesИзвестия Иркутского государственного университета: Серия "Математика"
The optimal control problem for a nonlinear dynamic system of a cascade type with endpoint and irregular pointwise state constraints (the so-called state constraints of depth 2) is studied.

The Pontryagin maximum principle from dynamic programming and viscosity solutions to first-order partial differential equations

open access: yes, 1986
We prove the Pontryagin Maximum Principle for the Lagrange problem of optimal control using the fact that the value function of the problem is the viscosity solution of the associated Hamilton-Jacobi-Bellman equation.

The Pontryagin Maximum Principle for Infinite-Horizon Optimal Controls [PDF]

open access: yes, 2003
this paper (motivated by recent works on optimization of long-term economic growth) suggests some further developments in the theory of first-order necessary optimality conditions for problems of optimal control with infinite time horizons.

On the sufficiency of Pontryagin's maximum principle

open access: yes, 2016
This work focus on sufficient conditions of optimality for an optimal control problem. A refined maximum principle condition which guarantees weak local optimality of control processes for affine control systems with a polyhedral set of controls is introduced. This refined maximum principle condition expresses that the control is uniquely de- fined for
