Authors: Kozenkova G L , Talamanov V N , Kozenkov V A , Kondratyev S I , Khekert E V , Modina M A 
Published: November 2021

Abstract
An extensive use of geophysical methods necessitates the development of new methods and improvement of existing methods for seismic exploration to provide reliable data on the structure of the environment in difficult geological conditions. Therefore, it is especially relevant to solve the problems arising in marine petroleum geophysics, which require constant improvement of the methodology and technology of work, and the development and implementation of the advanced seismic equipment. Pneumatic sources that use compressed air as a working medium are among the most effective non-explosive sources for marine seismic exploration. Pneumatic sources exhibit high-energy characteristics, reliability and versatility. Compressor equipment that provide pneumatic sources with high-pressure compressed air is relatively easy to embed into the marine vessel’s power system. The above requires the development and improvement of theoretical methods for studying dynamic problems of a liquid half-space with buried sources of various types. A theoretical description of the formation of an elastic signal in water is given in a number of works. However, the authors of these works do not perform the analysis of gas transportation. The paper considers a number of characteristics of gas flow at a subsonic speed along the high-pressure hose from a vessel’s compressor unit to a pneumatic source. The airflow rate in the receiver-pneumatic source system is determined, and the friction force at a quasi-steady isothermal mode of gas flow is calculated. The paper presents recommendations for planning geophysical works.
Improving the mathematical stability in the numerical simulation of the vehicle movement with an electronic movement control system
Authors: Balakina E V , Sarbaev D S , Sergienko I V 
Published: November 2021

Abstract
The aim of the study is to determine the influence of the calculated radius type on the calculated parameters of the vehicle movement, equipped with an electronic movement control system. A numerical simulation of the vehicle movement equipped with an electronic movement control system was carried out. Under calculated conditions, there are forces that disrupt the stable and controlled vehicle movement. The studies carried out have shown that in the numerical simulation of the parameters of the vehicle movement, the use of a dynamic radius instead of a rolling radius never affects the calculated values of the vehicle’s longitudinal shifts. In this case, the values of the lateral shifts and the turning angle of the vehicle on a dry hard surface change insignificantly, but there is a significant mathematical instability of the solution. On a wet hard surface, the influence of the calculated radii types on the characteristics of the simulated vehicle movement is preserved, but this influence is less pronounced.

Authors: Umnitsyn A A , Bakhmutov S V 
Published: November 2021

Abstract
This article discusses the work of an intelligent anti-lock braking system (ABS), in which electric machines and friction brakes act as actuators. Combining several actuators at one control object is a difficult task. One of the possible ways to solve it is the use of a control system based on fuzzy logic. The paper compares two tracking algorithms for controlling the actuators of the anti-lock braking system: - slipping control using mixed braking, with a control system based on fuzzy logic; - slipping control by means of braking by one actuator - friction brakes. Research results have shown that the use of mixed braking allows one to increase the performance of this system in various driving conditions.
Artificial intelligence for data collection and application of the probabilistic-logistic method in ship traffic control systems of seaports
Authors: Alekseev A A , Popov V V , Boran-Keshishyan A L 
Published: November 2021

Abstract
An increase in the number of ships, their sizes, speeds and displacement increases the number of accidents, especially in places with intensive shipping. Control over the positions of vessels, their movement, identification of intentions is exercised by the vessel traffic control system (VTCS). A new generation VTCS that can predict optimal and safest traffic patterns in water areas requires artificial intelligence and forecasting elements. Currently, the fifth generation VTCSs are being implemented. They can plan optimal and safe traffic patterns in the water areas, depending on various external factors controlled by artificial intelligence. The VTCS is a traffic control body. Due to the intensive ship traffic, the control over water traffic is becoming more and more urgent. The “probabilistic” model and the target-object can stop moving when the signal is lost, and it is impossible to continue moving along the same route with the same speed. This must be taken into account when using software [4,5]. The knowledge base for developing a logistic-probabilistic method is available, but there is no real application, due to the lack of massive implementation of artificial intelligence in the software.
Method of fragment based tracking of displacement of a large areal object in images
Authors: Lopatina V V 
Published: November 2021

Abstract
Automation of technological processes using computer vision systems necessitates fragment based tracking of the displacement of a large areal object in images. Examples of such processes are monitoring mooring operations, loading and unloading operations, analyzing the environment from the vessel’s bridge, and tracking berthing. These processes are cyclical in the maritime transport industry and thus require methods for automatic data analysis in 24×7 mode. The paper proposes a method of fragment based tracking of the displacement of a large areal object in images in real time. The algorithm that underlies the method enables tracking the object fragment using convolution of pixel matrices and ensures data processing by frequency methods, including computational operations using Fourier images. The developed method is applicable for real-time tracking the object in images, even when it can be hardly distinguished from the background. The method of tracking the displacement of a large areal object proposed in the study can be used in software and hardware meters for longitudinal and vertical displacement, which are used in the maritime transport industry.

Published: November 2021

Abstract
The paper considers the features and prospects of using neurocontrol methods in the context of development of technical solutions for transition to unmanned merchant vessels. The paper suggests a non-iterative training based artificial neural network (ANN), which is based on the principles of “direct inverse control” to control the speed and motion of unmanned surface vessels. The model is identified, and the structure of an artificial neural network and the diagram of the automatic control system (ACS) of an unmanned vessel (UV) are considered on the example of an electric propulsion vessel. A series of computational experiments is carried out to obtain a sufficiently complete training sample. and the control law is presented. The principle of the control system for an unmanned vessel is considered based on a neural network. At the next stage of the study, focus is on the synthesis of the optimal control system for UV navigation. The problem of the fastest motion of a third-order control object from one point (with any initial speed) to another (at the end point the vessel stops and the speed is zero) is considered. Based on the results of a series of experiments with the UV model, the controller parameters that provide the best indicators of control quality were set in the MATLAB Simulink environment.

Published: November 2021

Abstract
For industrial-grade manipulators, the study of trajectory tracking control issues provides an important guarantee for accurate and safe work. Therefore, the trajectory control input driving torque can meet the requirements of the robot arm to accurately track a given target trajectory, and the process of building a decision tree is a process of dividing the feature space. For a given training data set, a set of if-then is summarized the rule of. Based on this, this paper launches the research of multi-degree-of-freedom manipulator joint trajectory tracking control method based on decision tree. Based on the established kinematics and dynamics model of the manipulator, this paper uses a proportional-integral-derivative (PID) sliding mode controller based on the sliding mode surface of the manipulator to perform the trajectory tracking control of the end of the manipulator, and the simulation results of the improved sliding mode control are compared with the simulation results of the improved sliding mode control. The simulation results of the PID controller and the traditional sliding mode controller are compared. This paper finally verifies the effectiveness of the proposed new sliding mode controller based on the expanded state observer through the experimental platform. The speed and chattering problems of the trajectory tracking at the end of the manipulator are better than those of the controller on the experimental platform. Finally, this paper adopts the sliding mode variable structure control strategy combining the double-power reaching law and the improved terminal sliding mode surface to study the trajectory tracking control of the planar two-degree-of-freedom manipulator.
Research and Design of Java Timing Processing Method
Authors: He Weiwen 
Published: November 2021

Abstract
There are differences among programming languages. In contrast to C/C++ in Linux, standard Java timer has some issues, such as uncontrollable execution order, unpredictable start moment and running duration, when it’s applied to handle dense timing tasks. So it could not be directly used by some military applications with strict requirements on time sequence. In this paper, its root cause is analyzed, and then an improved method based on queue and delay feedback is presented, as well as its implementation flow chart. The test results show that, this method is able to not only ensure the correct execution order, but also reduce the uncontrollable delay. So it could satisfy the time sequence demand of military applications.
