Decentralized time-suboptimal control of multiinput-multioutput systems | |

In paper is considered decentralization robust optimal control of parametric and functionally by uncertain multicoherent plant. It is supposed that the scalar outputs of local subsystems are accessible measurement only each of which are used only in the subsystems. The purpose of control consists in translation of plant of an initial condition to final for the minimal time with the given accuracy. | |

Speed-gradient control for quantum-mechanical model of diatomic molecule | |

The observables control problem for finite dimensional quantum diatomic molecule is examined. Applying Speed-Gradient algorithm to quantum model a new control algorithm is designed. It is proved that the control goal is achieved for initial conditions from a pretty large domain of phase space. It is shown that the control function can be arbitrary small. The results are illustrated by the numerical example for HF molecule. | |

Chaos control of nonlinear current oscillations in semiconductor heterostructures | |

We study autosynchronization by time delayed feedback control of chaotic spatio-temporal patterns in spatially extended semiconductor models. Different control schemes, e.g., a diagonal control matrix, or global control, or combinations of both, are compared. In particular, we use two models of semiconductor nanostructures which are of current interest: (i) superlattice, (ii) double-barrier resonant-tunneling diode. | |

Time delayed feedback control of chaos by spatio-temporal filtering | |

Time delayed feedback control is employed to stabilise time periodic patterns in a reaction-diffusion model with global coupling. The control performance is increased by several orders of magnitude by suitable filters and couplings which are based on the Floquet eigenmodes of the unstable orbit. The essential mechanism for the improvement of the control performance is attributed to a phase synchronisation mechanism between the target state and the control loop. | |

Sufficient conditions for elliptic problem of optimal control in the Sobolev space W, where _{0}^{1,2}(I)I is a bounded interval in R | |

The paper is concerned with the local minimization problem far a variety of
non Frechet-differentiable Gateau functional
in the Sobolev space ,
where u is the solution of the Dirichlet
problem for a linear uniformly elliptic operator with nonhomogenious term
f and
is the norm generated by metric space .
We use a recent extension of Frechet-Differentiability (approach of Taylor mappings see [1]),
and we give various assumptions on v to guarantee
a critical point is a strict local minimum.
Finally, we give an example of a control problem, where classical Frechet
differentiability can't be used and their approach of Taylor mappings works.

Robust Control Algorithm of Uncertain Object without Measurement of Derivatives of an Adjustable Variable | |

Robust control scheme of uncertain object without measurement of derivatives of an adjustable variable (an output of object of control), providing under the assumptions to the object of control given in the paper, limitation of an adjustable variable and its convergence to some limited invariant set is offered. Procedure of synthesis is based on popular Morse approach, which in the literature has received the name of "adaptation algorithm of the high order". In contrast to adaptation algorithm of the high order, the offered scheme of robust control allows to synthesize regulators less bulky in dimension. In the paper the results of computer modelling, which illustrate the efficiency of the offered control scheme are given. | |

The Chaos of the Market and Phenomena of Business | |

There is a thesis about universality of mechanisms of the chaos and regulating state which distributes on all world's appearances and studies in that work. The differences between steady and aperiodic state of system is determined by a scale and axises of coordinates. It proposes, that the state of equilibrium and non-stable behavior of the system is a phase of some process and depends on level of provideness of resourses the elements of this system. The conception about phenomenon of chaos be used in applied purposes. For example - in forecasting of probable seat or moments of crisis. | |
