Metel'skii and S. A. Minyuk Belarus State Technical University, Minsk, Belarus Grodno State University, Grodno, Belarus Received February 1, 2002 INTRODUCTION Consider the observation system x _ (t)= A(t)x(t);t 2 T =[t ;t ]; (1) 0 1 with output y(t)= c(t)x(t);t 2 T; (2) where A(t)is an n n matrix and c(t)is a row n-vector with continuous entries on T . There are two approaches to the statement of the observation problem for system (1), (2). The rst approach assumes [1, p. 68 of the Russian translation; 2, p. 188] a one-to-one correspon- dence between the set of initial states x (t )= x and the set of outputs 0 0 y(t)= y t;x = c(t)x t;t ;x ;t 2 T; 0 0 where x (t;t ;x ) is the solution of the vector equation (1) with the initial condition x (t )= x . 0 0 The second approach, suggested in [3],
