Grachev, Associate professor, ga150161@mail.ru, Tula State University Parameter Identification of Linear Dynamic Systems by Fast Genetic Algorithm A fast genetic algorithm using special reserve elite population for parameter identification of linear dynamic systems is presented. System identification problem can be treated as an optimization problem, where the goal is to find set of parameters that minimize the prediction error between the measured system output and model output at each measure time-step. The classical identification methods, such as least-square method, are calculus-based search method. They have many drawbacks, for example, required a good initial value of the parameters, knowing of the gradient (higher-order derivatives) of the objective function, and possibility to fall into a local minimum. Genetic algorithms (GA) are a family of general stochastic search methods, which can be viewed as computational models of Darwinian evolution theory. However; classical GA are effective methods in the off-line optimization of system identification problems, but they are not too demanding, as could be natural to expect, in terms of their needs of computational power, for real time identifications. In this article we present some modification on the classical GA, which made it applicable in the real time optimization. The basic principle of this genetic algorithm is by creating an array called reserve elite population. This population contains the best fitted chromosomes from the previous optimization cycles, as described through the article. The simulation results are showed that proposed fast genetic algorithm result accepted solutions times. This algorithm may be used in real time systems identification applications. P. 915 |

The novel approach of above mentioned problem solution is suggested, which is based on so-called individually adopted intellectual human operator actions monitoring and support.

Kozharov, postgraduate student, i.kozharov@gmail.com, Analytical Information Security Systems Department, Southern Federal University, Taganrog, Russia Adaptation of Cargo Flow in the Mechanical Transport Systems Based on the Experience of his Observations In this paper we investigate the adaptation cargo flow to the emergence of local overloads in the mechanical transport system. The adaptation mechanism is based on the deflection of bypassing sections with high risk of occurrence of congestion cost. Routing is a means of flow control. The duplex adaptation procedure is proposed here. At the top level routing strategy is built by an expert, which reduces the flow in the network segments with predicted congestion. On the lower level of transport controllers the system strategy is implemented by dynamic routing. The forecast is based on the experiences with expert intensity of traffic in the system. The modified version of case analysis, which uses the concept of pictorial representation of situations, is offered. In contrast to the known methods, the figurative description of precedents increases the reliability of decision-making. The result of case analysis sets the time dependence of transport costs on separate network segments. The modification of the algorithm of dynamically build routing tables by controllers transport network is proposed. The algorithm considers the temporal dependence of the weights of transport network edges. A distinctive feature of this algorithm is the comparison of cost and time of transportation that allows finding the compromise between these two indicators. The relations to evaluate the effectiveness of the proposed method adaptation are given. P. 2328 N. N.

Tuphanov1, Post-graduate Student, Researcher, ituphanov@gmail.com The Method of Tracking Control of Autonomous Unmanned Underwater Vehicle Motion In this paper a new method of tracking control system of autonomous underwater vehicle (AUV) motion along the complex spatial trajectories is proposed. This method is based on using of additional loops of automatic formation of program signals in AUV control system (CS). First loop changes the desired trajectory of AUV movement so that with taking into account of dynamic error of its CS the AUV can movement along desired trajectory with desired accuracy. The second loop tunes the program AUV velocity (movement mode) along desired trajectory so that taking into account the restriction of thrusters power. As a result it becomes possible to provide the AUV movement along desired trajectory with maximal velocity and desired accuracy. The work of these additional loops provides the AUV movement along the desired spatial trajectory with high velocity without sacrificing of desired accuracy. The realization features of the proposed CS and results of experimental researches that confirm of its high efficiency are presented. P. 4656 |
V. M. Dorozhko, Senior Staff Scientist, bendor@iacp.dvo.ru, Institute of Automation and Control Processes, Far East Branch, Russian Academy of Sciences (IACP FEB RAS), Vladivostok, Russia Dynamic Load of the Abnormal Wavelet-Wave on the Motionless Obstacle The article is devoted to study of the impact of a rogue wave with the shape similar to the Morlet wavelet on stationary obstacles which imitate the elements of ship hull or hydraulic engineering marine structure. Thus we use the term the abnormal wavelet-wave for such rogue wave. The main idea is to perform CFD-simulation of evolution of abnormal wavelet-waves with the height up to 2030 meters to obtain pressure fields on vertical or horizontal obstacles. To simulate this process the propagating surface wavelet-waves were created in a numerical tank and it is shown that as a result of nonlinear transformation their height may grow to 2030 meters. The initial amplitude and length of the wavelet-wave which cause the growth of its height to abnormal 2030 meters are established. The conditions for self-similarity of wavelet-wave profiles during the process of their nonlinear transformation are derived. To estimate the maximal pressure values created by abnormal wavelet-wave the vertical wall was introduced in front of the wavelet-wave when it reached its maximal height. To study extreme pressure values for horizontal obstacle they were positioned at the location of the breaking wavelet-waves when their flow attains the maximal velocity. It was found that the highest (2,0?106...1?107 Pa) pressure takes place on the vertical obstacle. At the junction of a horizontal obstacle and a vertical wall (a corner obstacle) a breaking wavelet-wave creates considerable pressure values up to 4?106 Pa as well. The evolution of abnormal wavelet-wave from initial to maximal height takes no more then one wavelet period. During this time the abnormal wavelet covers the distance not longer then length of central wave. The impact of abnormal wavelet-wave creates on sea objects the pressure exceeding the design parameters of ships and sea structures. Thus the case of a sea object to experience abnormal wavelet-wave is distinguished by the suddenness of the accident and puts its structure into immediate danger. P. 5662 |

Noskov, Associate Professor, noskov_rnstu@mail.ru, 3D Vision-Based Unmanned Vehicle Navigation and 3D Reconstruction of Environments In this article we investigate the problem of autonomous flight of small-sized helicopter type unmanned vehicle in apriory indefinite GPS-denied outdoor and indoor environments. The main critical tasks in this case, except for the problem of flight stabilization, are the problem of determining of the current linear and angular coordinates of the control object and the formation of 3D model of the surrounding space in the fixed coordinate system. An approach we describe is aimed to solve inflight the 3D vision-based vehicle localization problem and 3D reconstruction of static indoor environments. Two variants of 3D image formation of the surrounding space are considered: using 2D laser rangefinder UTM-30LX, while 3D image is obtained by the rotation of the vehicle around the vertical axis, and using 3D rangefinder with active backlight Asus Xtion Live Pro. Dependence of coordinates calculation errors on the sensors error are obtained, performance of proposed algorithms for used computational tools are evaluated. The structural and functional circuits of onboard control system and the results of field tests of developed algorithms, software and hardware tools are given. P. 6268 I. O.

Kostishin1, Postgraduate, job.max@me.com, The Algorithm for Generating and Outputting the Image Map Navigation Systems Manned Aircraft In this article, the authors consider how to display the navigation frames displayed onboard vehicle display aircraft. Existing methods for displaying navigation information enable you to visualize on board the aircraft schematic view which gives a pictorial representation of the earth's surface, is detailed enough and increases the likelihood of an emergency during flight, in the conditions of the mountainous terrain in poor visibility and low altitude. To improve the safety and reliability of the aircraft, the authors propose to implement bot features imaging, which will combine visual and graphic images (flight and navigation, meteorological radar) and other types of information. Just a visual display area maps reduces crew workload information and provides the ability to maintain the necessary concentration of pilots to fly during the flight. P. 6872 |
