ABSTRACT

The state estimation problem of a linear dynamic distributed system in a bounded domain with known boundary, but unknown initial conditions is considered. The finite-dimensional model of the process, obtained by the Galerkin method, and the state estimation of the model by the ellipsoids method are used for solution of the problem. The features of the proposed approach are discussed and analyzed by two examples of solution of the problem of estimation of positions and velocities of a string and membrane.
