Synthesis of Intelligent Discrete Algorithms for Estimation with Model Adaptation Based on the Combined Maximum Principle

Abstract

The paper considers the problem to estimate the parameters of the motion of maneuvering targets. The structure of the filter for estimating the parameters of motion is determined by the mathematical model of the motion. At present time the kinematic models are widely used, but they do not fully correspond to the observed dynamics. This may lead to divergence of the estimation process and failure of the computational procedure. New dynamic filters of the combined maximum principle with the dynamic model of motion possess higher accuracy and stability and smaller amount of computational costs in comparison with common filters. The parametric adaptation of the procedure is carried out using fuzzy logic.

Combined process of vibratory processing and oxidation with the use of polymeric environments

“…When applying oxide coatings on aluminum surfaces, the choice of the working medium is primarily determined by its physicochemical properties [14][15][16][17][18][19][20].…”

Theoretical foundations of modeling the process of transport vehicles steel ropes structural defects formation

“…For designing the mathematical model of splicing (coalescing), we consider the wellknown calculation scheme for determining the force factors acting in steel rope elements [23][24][25][26][27][28][29][30][31]. We introduce a coordinate system in each cross section of steel rope element t, n, a (trihedral -), so the axis t will be sent tangentially, а n and в, respectively, along the main normal and binormal to the helical axis of its element.…”

Development of a furrow irrigation method

“…The purpose of this study is to develop agrotechnical measures to maintain constant soil moisture throughout the growing season with economical consumption of irrigation water. [13][14][15][16][17][18][19][20]. Irrigation rate -(or irrigation rate) is the amount of water of a certain quality that must be supplied for the entire irrigation period per hectare of irrigated area in addition to its natural reserves in the soil in order to obtain the planned yield in specific climatic conditions.…”
