Synthesis of Optimal Distributed Measurement Systems for Control of an Elastic Object

Abstract

Effective control of an elastic space vehicle is possible only on the basis of exact information on its elastic oscillations. Exact estimation of these oscillations is possible via a distributed system of measuring instruments installed in different points of the elastic design. In recent years, new types of inertial measuring devices came into use like micro-electro-mechanical (MEMS) gyroscopes and accelerometers. Significant progress in the development of on-board computers allows the use of modern means of filtering algorithms, based on numerical integration of a large number of differential equations in real time. Miniaturization of sensors and the decrease of their power consumption increases admissible quantity of used sensitive elements and reduces restrictions for their placement. This article presents new results on optimization of placement of system of sensors on an elastic controlled object.
