To improve the accuracy of the aircraft navigation system error correction in the output signal is used. The errors of the navigation complex are estimated by using a nonlinear Kalman filter. It is proposed to use a nonlinear model constructed by the method of self-organization as a model of the process being evaluated. The effectiveness of the self-organization algorithm in comparison with the genetic algorithm and the neural network is confirmed by the results of mathematical modeling.

An algorithm for constructing a forecast of the electricity price with the introduction of an aggregated model that includes the accounting of correction components according to the forecast of influencing factors is proposed. The algorithm provides a preliminary determination of the dominant factors depending on the specifics of solving the problem, including a specific region, the depth of the forecast, the established regional conjuncture of the electricity market. Based on the selected factors, a forecast model in the form of time series is constructed. The proposed forecast formation mechanism is implemented by the use of artificial neural networks (ANN). The structure of the ANN allows the convolution of models of influencing factors and the model of the main variable in a single time series of the predicted variable. Such aggregated forecast model makes it possible to significantly increase the accuracy of the forecast in constantly changing behavior conditions of micro- and macroeconomics, climate, production structure and consumption of energy resources, which is confirmed by the example of the Belgorod region.

The synthesis problem of adjuster for software automatic escorting of a ground mobile object using a surveysearch system of an aircraft is considered. The calculation of the control function is carried out by the method of the inverse dynamic problem separately for two angular channels. It is proposed to take into account the restrictions on the magnitude of the control action and on the angles of the line of sight, as well as to use the nonlinear Lewis equation with a correcting differential term as a reference equation.
