Optimal control of a differential-difference parabolic system with distributed parameters on the graph

Abstract

In the paper be considered the problem of optimal control of the differential-difference equation with distributed parameters on the graph in the class of summable functions. Particular attention is given to the connection of the differential-differential system with the evolutionary differential system and the search conditions in which the properties of the differential system are preserved. This connection establishes a universal method of semi- digitization by temporal variable for differential system, providing an effective tool in finding conditions of uniqueness solvability and continuity on the initial data for the differential- differential system. A priori estimates of the norms of a weak solution of differential- differential system give an opportunity to establish not only the solvability of this system but also the existence of a weak solution of the evolutionary differential system. For the differential-difference system analysis of the optimal control problem is presented, containing natural in that cases a additional study of the problem with a time lag. This essentially uses the conjugate state of the system and the conjugate system for a differential-difference system — defining ratios that determine optimal control or the set optimal controls. The work shows courses to transfer the results in case of analysis of optimal control problems in the class of functions with bearer in network-like domains. The transition from an evolutionary differential system to a differential-difference system was a natural step in the study of applied problems of the theory of the transfer of solid mediums. The obtained results underlie the analysis of optimal control problems for differential systems with distributed parameters on a graph, which have interesting analogies with multiphase problems of multidimensional hydrodynamics.

A problem of the equidistant deployment for discrete-time multiagent systems

“…Introduction. Problems of formation control of mobile agents have been intensively studied in past decades due to their broad applications in various areas (see, for instance, [1][2][3][4][5] and the references cited therein). The goal of formation control is to design a distributed control algorithm for each agent providing desired group behavior of the whole system.…”

“…In addition, it is supposed that each i-th auxiliary agent knows values i − m (σ) i and l (σ) i − i. Under Assumptions 3 and 4, instead of (4), (5), the following control protocols can be applied:…”
