This paper develops the theory of vibrational control of nonlinear time lag systems with arbitrarily large but bounded delay. Averaging theory for fast oscillating, differential delay equations is presented and then applied to vibrational control ...

The recently developed thermodynamically constrained averaging theory is briefly summarized as a tool for the building of rigorous macroscale models of transport phenomena in complex systems. The specific case of thermal transport in a single-fluid-phase

Group theory and propagation of operator averages
Journal of Mathematical Physics, 1975The propagation of operator averages, which is the basis of French’s spectral distribution method, is reformulated in the framework of group theory. The concept of complementary groups is extensively used. It is shown that the possibility of propagating averages is intimately connected with the absence of state labeling problem. The construction of the

Prediction theory for autoregressivemoving average processes
Econometric Reviews, 1988This paper reviews statistical prediction theory for autoregressive-moving average processes wing techniques developed in control theory. It demonstrates explicitly the connectioluns between the statistical and control theory literatures. Both the forecasting problem and the Single extraction problem am considered, udng linear least squares methods ...

Elements of Thermodynamically Constrained Averaging Theory [PDF]
, 2014 Mechanistic computational modeling of environmental systems presupposes the existence of a properly posed set of equations that adequately describes the underlying physical, chemical, and biological processes at time and length scales consistent with the problem being addressed.

Resonances in Multifrequency Averaging Theory
1994The Whitham method allows to obtain rapidly oscillating asymptotic solutions of nonlinear equations with a small parameter e which characterizes the dispersion. The principal term of such asymptotic solutions can be represented in the form $$ u = f\left( {\frac{{S\left( {x,t} \right)}}{\varepsilon },x,t} \right)$$ (1.1) , where f (τ, x, t ...

Theory and Application of Average fs-Aggregate Algorithm
2021Generally in our day to day life we come across the real life situations when right decision making becomes difficult. In different fields like economics, social science, medical science, environment, where such complicacy arises and involves uncertainties. The conventional mathematical methods are unsuitable to solve such problems.

Application of the Averaging Method in Bifurcation Theory
1998The averaging method is very famous in non-linear vibration. This chapter describes it from the viewpoint of geometry and Poincare mapping. We will introduce it according to the theory of KBM (Krylov, Bogoliubov, Mytropolisky). This method is very effective for the weak non-linear system and the linear disturbed system [1].
