Constructing of Piecewise Constant Control in the Problem of Dynamic Positioning of Ship
The paper deals with the results of solving the problem of control synthesis performing dynamic positioning of ship in a point. The problem of simple dynamic positioning, which is in alignment with the center of mass of the vessel with given point waters (center position) for the given requirements for the orientation course is considered. The solution of this problem is provided by use of control on the basis of feedback that asymptotically stabilizes the position and orientation of the ship. To justify the control law, which is based in a discrete form, Euler discrete approximation of the original continuous system is constructed and the method of recursive procedure of backstepping is applied. This procedure allows to build a controlled system that can be represented as a cascade connection of several subsystems. For each subsystem, the stabilizing control and the Lyapunov function are built. At the final step of the recursive procedure, a control law for the entire system and the corresponding Lyapunov function is constructed. Thus, the structure of the found control law essentially depends on the Lyapunov function used at each stage of the procedure. We justify the use of a new class of Lyapunov functions in the form of vector norms for solving this problem, which is used in comparison to previously known works with class of quadratic Lyapunov functions and allows us to simplify the control structure and improve its properties, such as the speed of convergence of the process at a given position. The results of numerical simulations, confirming a higher effectiveness of the proposed control law in comparison with the known results are obtained. Dynamic positioning, piecewise constant control, backstepping technique, lyapunov function.

Synthesis of a Fuzzy Controller for Control of Ship Hoist
The present paper deals with a mathematical model of the system which is comprised of a ship hoist and a cable connecting the remotely controlled underwater vehicle with a surface ship; a fuzzy controller is synthesized to control the ship hoist allowing the minimum impact of the cable to the underwater vehicle.The mathematical model of the cable is represented by the Nsystem of the hinged rails (links); at this, the length of the first link and the link number allow their reduction over time. To model the ship hoist, a simplified model is applied. Recommendations are made to determine the membership functions for input and output variables of the developed controller, and to synthesize its rule database. The Mamdani algorithm is employed for the fuzzy logic output. When setting the membership functions and synthesizing the control rules, the restrictions for the cable strength and hoist persistence are taken into account. The paper gives the results of comparison of the ‘proportionaldifferential’ model with the fuzzy controllers. A computer program is developed where the performance of the hoist and control system within the ‘surface ship  cable  underwater vehicle’ system is simulated. To identify the hoist, we have used the actual features of SVL4 hoist which is ‘Simbiya’ company produced. To implement the fuzzy modeling process, we have employed tools from MathWorks MatLab mathematical software package including Fuzzy Logic Toolbox, a specialized bump pack. Cable, ship hoist, fuzzy controller.

Spectral Method of Measurement of the Led Thermal Resistance and Estimation of the Optimal Performance
The computer simulation helped the authors in studying the kinetics of the LED heating by the pulsewidth modulated power varying harmonically. The programming model relies on a principle of the thermoelectric analogy saying that the heat dissipation processes on the path “chip  substrate  case  radiator  environment” are similar to electrical processes in the equivalent circuit, which is a set of serialconnected RCchains. The task of simulation was to validate the LED thermal resistance measurement method based on heating by PWM power, as well as to study the effect on the accuracy and sensitivity of the method parameters such as heating pulse repetition period, frequency, and modulation coefficient, the number of heating pulses per modulation period. The simulation results shows that the method has an accuracy of 3%, and this value is independent of the heating pulse repetition period ranging between 80200 ms. Sensitivity of the method depends on the modulation frequency of the heating power and heating pulse repetition period. It decreases with increasing modulation frequency, increases with the decrease of the repetition period at constant amplitude of oscillation pulse duration.

Motion Modes of Shock System for Fluctuating Force Linear Function With Changing Characteristics
Multiple technological processes are often related to using shock systems for performing of cyclic shocks on the object. Research of such systems’ dynamics, stability of motion, shock activity level requires examination of shock processes in systems with different structures. At the same time, a number of problems, confining an area of application of shock systems, arise. They are the following: finding of solutions by exact methods; taking into account complimentary nonliner factors; analysis of transient processes; detection of limit cycles of motion. These problems can be solved by means of developing the effective dynamic system simulation procedures based on the adequate mathematical models, process visualization, and representation and good processing of simulation results. The paper [1] provides an examination of the model of shock system, as well as the definition of its parameters, ensuring a required low of motion. However, a considered piecewise constant force impact may be applied to an ideal situation that is difficult to implement with a real system. Thus, it is required to know how the change of force impact would effect the mode of striker’s motion. The present paper deals with a model for shock system at force impact as linearly increasing and linearly decreasing function when force impulse, duration and period of the force impact are constant as at the piecewise constant function. A mathematical model for the shock mass motion under condition of collision with rigid barriers is given. The modeling of shock system motion at the forceimpact piecewise constant, linearly increasing and linearly decreasing function is implemented. The comparative analysis of presented simulation results is performed. The motion mode of shock system at linearly increasing and linearly decreasing functions has been changed against the mode at the forceimpact piecewise constant function (although the force impulse was constant in both cases). Following the results of implemented work, it may be deduced that the changing the force linear function characteristics, when impulse and duration of force, and part of cycles are constant at an appropriate systemparameter option, does not misrepresent the cyclic mode of shock mass motion if the process would be estimated at such criteria as velocity of shock to the right barrier, implementing of one impact per a cycle at the maximal velocity, and a cyclic behavior of impact.

Mathematical Simulation of Power Conversation Systems for Micro Grid
Mathematical model of AC/DC/AC converter with energy storage device is developed on the base of the bridge element concept. This model is intended for the analysis of conducted interference at the designing stage of micro Smart Grid, which contain AC/DC/AC converters, as well as for the emulation of the control object at the software development stage of microcontrollers.Bridge element (Belement) is a generalized model of the mphase bridge converter of electric power, in which transistors are modeled by ideal switches. Rules to represent a graph of the equivalent circuit of AC/DC/AC converter with energy storage as a set of subgraphs corresponding standardized bridge elements are developed. Application of these rules provides correctness of algorithm functioning of forming and solution of differential equations of the equivalent circuit at any state of the switches automatically.Computational aspects of the algorithm have been investigated on the example of mathematical simulation of AC/DC/AC converter with MPI distributed computing technology. Preliminary results showed that increasing of the simulation speed may be achieved by application of parallel computing technology for solution of the complete differential equations system formed on the Belement base. Elementwise forming and solution of differential equations systems does not increase the computational efficiency. Additional studies are required for final confirmation of these results.

Numerical Investigation of the Temperature Stratification
The intensity of heat and mass transfer in devices based on the gasdynamic temperature stratification, for example, in a supersonic pipe temperature stratification (in the Leontief’s pipe) is determined by the heat flow through the separation wall between subsonic and supersonic flows. This paper presents the mathematical modeling and numerical study of heat transfer in devices of gasdynamic temperature stratification using passive stimulation techniques. The efficiency of heat pipes (HP) and the metal edges of the same configuration were researched. Mathematical modeling was performed using a mathematical model. The mathematical model includes differential equations that describe the motion and heat transfer in the boundary layer; equations for calculation of heat transfer processes in heat pipes; equations to calculate the heat flow between subsonic and supersonic flows in the device of gasdynamic temperature stratification.It was found that the intensification of heat transfer devices based on the gasdynamic temperature stratification (in the Leontief’s pipe) through the use of heat pipes is increasing up to 3 times. It was established that the use of heat pipes with a wick of material copperwater is more of using efficiency of heat pipes with the working material in the aluminumacetone up to 1.05 ... 1.12 times.

Questionanswer Modeling of the Operational Spacein Designing the Family of Automated Systems
For last 20 years, the successfulness of developing the software intensive systems (SIS) has been associated with a very low degree of a success (approximately 35% in accordance with universally recognized statistics of Standish Croup company), and it is an important reason for searching of new approaches to occupational activity in this subject area which enough fully reflects problems of occupational activity in humancomputer environments. Negative influences of human factors (misunderstanding, ambiguity of reasoning and the others) are being recognized as basic reasons of unsuccessfulness in creating and using of SISs and automated systems (AS) as a subclass of SIS, and it inevitable concerns relations of the human with the software. A very important direction of an implementation and improvement of the humancomputer activity is bound with discovering, representing and evolving an occupational experience. The special role of interactions with experience in humancomputer environments is confirmed by active evolving of the subject area “empirical software engineering” in the frame of which the special kind of “metrology” is developed. This subject area is also bound with the creation and use of the Experience Bases and Experience Factories and with methods and means of “experimenting” in humancomputer environments. Told above includes sufficient arguments to count the creation of innovative methods and means of conceptual experimenting in humancomputer environments is topical.Formalization of conceptual experimenting is implemented with using a system of rules of the generated grammar which shall include the sets of rules specifying a reflection of all components of professional work onto a questionanswer memory.
