SYNTHESIS OF OPTIMAL CONTROL STRATEGY BY DAMPING A VIBRATION OF EARTH SATELLITE WITH A GRAVITY-GRADIENT STABILIZATION WITH INCOMPLETE INFORMATION ABOUT THE STATE

摘要

The synthesis control strategy problem for damping vibration concerning center of mass of a satellite with a gravity-gradient stabilization is investigated. It is supposed, that only part of state vector component is measured. The case of inexact measurements of components of a state vector is considered. Various versions of a structure of measurements are investigated. The criterion of quality is energy consumption in electromagnetic control device. Offered outcomes are new and may be used at designing of control systems nano satellites and pico satellites for which the problem of control under the inexact information is actual. For the solution of a problem new method, developed by authors, of synthesis optimal control strategy for quasi linear stochastic systems with incomplete information about the state is used.
