The problem of noise droop in the measured signal at the input of the circuit, which includes a PID controller, a frequency converter, an asynchronous motor and a compressor for supplying air to the apparatus, is considered. It is proposed for noise droop to introduce a nonlinear dead zone (NZ) at the controller input, which is determined by the requirements of the control accuracy in a stationary mode and is implemented using an approximating nonlinear function with saturation. As a result, noise droop is achieved at the NZ output by error asymptotic approximation to zero, in contrast to the threshold noise suppression. Research is carried out and results that reflect the effectiveness of the proposed solution is obtained. Keywords approximating nonlinear function, dead zone, PID controller, noise droop coefficient, transient process

A method for predicting the trajectory of an unmanned vehicle using graphs and a network of long short-term memory (LSTM) is developed. The learning model of LSTM network uses an encoder and decoder structure. Based on the graph and the attention mechanism, the encoder encodes information about the received trajectory to form a feature vector, which is puted to the decoder to predict future trajectories. To cope with multimodality in predicting vehicle maneuvers, module of convolutional network (CNN) is used. These two networks: LSTM and CNN are integrated for multimodal trajectory prediction.

The analysis an influence of reflections from the underlying surface, atmospheric noise, the Earth’s surface, cosmic noise and signal attenuation of the signal the atmosphere, as well as the flight dynamics of the aircraft (AC) on the signal/noise ratio and, accordingly, on the accuracy of AC navigation definitions by using consumer equipment of the satellite radio navigation systems. The analysis an influence of reflections from the underlying surface on the equipment operation quality of the satellite radio navigation systems consumers is carried out by using the Beckman model, in accordance with the earth’s surface appears to consist of flat faces with an arbitrary slope. It is noted that reflections from the underlying surface have a greater effect on the quality of functioning of the consumer equipment of the satellite radio navigation systems in the tracking signal mode than in the detection mode. In this case, the influence of reflections increases with decreasing flight altitude and an increase in the angle of heel of the AC in the direction of the navigation spacecraft.

An algorithm for controlling the number of revolutions of the electric motors for the liquid pump and the radiator fan, depending on the temperature of the internal combustion engine coolant is proposed. This algorithm is stir up by the Arduino MEGA 2500 microcontroller in conjunction with the motor driver.
