Управление крупномасштабной системой по Ð²Ñ‹Ñ Ð¾Ð´Ñƒ на основе редуцированной математической модели системы

Abstract

Ð’ данной работе рассматривается задача синтеза Hâ‚‚, H∞ - регуляторов по Ð²Ñ‹Ñ Ð¾Ð´Ñƒ с применением методов редукции. Проведено исследование Ñ€Ð°Ð·Ð»Ð¸Ñ‡Ð½Ñ‹Ñ Ð¼ÐµÑ‚Ð¾Ð´Ð¾Ð² редукции в подпространстве Крылова и методов Hâ‚‚, H∞ -оптимизации.

This thesis considers the output H-controller synthesis with applied reduction methods. The study of different reduction methods in Krylov subspace and methods H₂-, H∞ -optimization. Define a general description of the methods and features of their implementation. The computation simulations of controllers developed for reduced models and applied to the originals ones show high reproductibility of the system performance. The International Space Station module is considered as a large-scale system for computation. A number of methods evaluated in terms of parametric features. The problem of the maximum reduction of the order with saving the specified accuracy modeling of transients and the problem of the synthesis controller stabilization output control system using reduction methods. As example, H₂-, H∞ - controllers, illustrating the results.
