CORRECTION

In our article (S. V. Emel’ianov and M. A. Bermant, “On the question of constructing high-quality automatic control systems for objects with varying parameters”), published in DAN, vol. 145, no. 4, 1962, the following corrections must be made.

P. 749, in formula (4), where it was printed

\[ f_n^0=\frac{1}{c_n}\sum_{1}^{n-1} c_j x_j, \]

it should read

\[ f_n^0=\frac{1}{c_n}\sum_{1}^{n-1} c_j x_{j+1}. \]

P. 750, line 1, should read: “Let the free oscillations of the tracking system be described by the system...”

P. 750, in the example, where it was printed

\[ a_1=+\omega_0^2,\qquad b_1=-\omega_0^2, \]

it should read

\[ a_1=\omega_0^2,\qquad b_1=+\omega_0^2. \]
