A modification of the star map preprocessing method based on the Sobel operator is proposed. Since the star tracker images are subjected to varying degrees of light scattering to eliminate the region of brightness at the center of the star, avoid the influence of star point overexpansion and retain more information about star points characteristics, edge detection and stylized morphological processing are performed. The improved method demonstrates good adaptability and accuracy in extracting reliable information. Keywords star map recognition, centroid extraction, scattered light, Sobel operator, morphology

An aircraft navigation complex as a part of an inertial navigation system, a satellite navigation system and an adaptive nonlinear Kalman filter is considered. In the Kalman filter, when the estimation process diverges, the model is constructed using an evolutionary algorithm. The used divergence indicators analyze the measured signals; the directly unmeasured state variables are not examined. A divergence criterion of directly unmeasured state variables is proposed on the grounds of the reduced measurements and the variances of the reduced measurement noises. The algorithm modification effectiveness is demonstrated by using the flight experiment data.

The features of the multi-parameter process control based on individual observations, when sampling during monitoring is impossible due to the complexity of measurements or is not economically feasible, are considered. Monitoring of multidimensional scattering usually by using the generalized variance algorithm is carried out, however, when controlling for individual observations, a number of problems arise. An approach to estimating the covariance matrix to solve this problem is proposed. Keywords multivariate statistical control, generalized variance, sliding range

The parametric sensitivity of the control quality factors is investigated; the most significant parameters of the regulator settings for the transient and steady-state modes of the system are validated. The range of minimum and maximum values of the sensitivity coefficient, at which the quality indicators are sensitive to variations in the tuning parameters of the investigated regulator is established. The results of the analysis permit to choose acceptable ranges for the parameters variation of the regulator settings at the stage of developing multi-mode control systems.

To determine the errors first component in the tolerance field structure of the inter-transition size the knowledge base of the production technological preparation by seven levels of its basic objects of functionally different types is used. The task is solved in the working space of working machines, in the structure of which two technological schemes are built: for basing the initial blanks in working machines and for basing form elements in working machines and their geometric forming on working machines. Technological schemes for basing the initial blanks into working machines in the general case have a significant impact on the geometric and dimensional errors (the considered component) of the shape elements to be converted in the technological schemes for basing form elements into working machines and their geometric forming on working machines. It is shown that the determination of the errors first component in the tolerance field structure of the inter-junction size must be carried out by means of specialized intelligent control and measuring systems, embedding them in the structure of working machines. Determination of the first component in the tolerance field structure of the inter-transition size is relevant, has scientific novelty and practical significance.
