CORRECTION OF THE VERTICAL CHANNEL SINS FROM NOISY INFORMATION ON THE HEIGHT AND VERTICAL SPEED ON THE BASIS OF H_2-OPTIMIZATION METHOD

摘要

The report deals with the problem of constructing corrective controls for vertical channel SINS, which is unstable without the introduction of such controls. The problem is formalized as the problem of synthesizing feedback using the information about the height and vertical speed extracted from the respective transducers at a relatively high level of noise. Consideration of the spectral characteristics of the noise allows us to introduce this problem to a well-known problem of H2-optimization with additional requirements of astatism, which is necessary to eliminate the constant error components of the vertical channel, and consideration of control delays introduced by the calculator. A numerical solution of the problem is given and modeling of operation of corrective SINS for horizontal perturbed motion at a given height is carried out.
