This article discusses the features of the power plant control based on renewable energy sources for additional and emergency power supply of surface robotic systems. This kind of integrated power plant can be built on the basis of wind and solar energy converters and produce at least 10-15% of all electrical energy required for the vessel. For the most important element of the KSEU - wind power plant (wind), the Electromechanical torque control on the shaft of its rotor is considered. For this purpose, firstly, the problem of controlling the angular velocity of the rotor rotation by means of variable geometry elements (IEG) of the VEU of perspective type is solved. As an IEG, the tunable distance from the lower part of the rotor to the upper part of the lower guide structure of this wind turbine is considered. Simulation of the equations of the controller for the particular case of stabilization of the rotation speed of the rotor. Secondly, the structural scheme of electrical control of the output characteristics of the wind turbine is justified and the method of selection of some key elements of this scheme is given. Features of realization of the electric circuit of connection of VEU, solar panels (SP) and diesel generator set in uniform KSEU are considered. It is shown that the constructed integrated control system of wind turbines is able to effectively solve the problem of parrying external wind disturbances.

The paper presents a method for decomposition of a complex dynamic system with a network architecture based on the Crohn's diakoptic approach. The proposed method is aimed at the allocation of independent network segments, the removal of which from the general structure will not affect the overall performance of the system. Segments are formed as simple paths in the graph model of the system with the least weight of the incident edges and checking the condition for maintaining the product flow balance in the application to the transport task. In general, the decomposition method presented allows us to divide a complex technical object of the network architecture into subsystems, simplifying the process of analysis and management. In the case when the common control task and the dynamics of interaction of subsystems allow the system to be broken up into unconnected segments, or to limit interaction over certain lines, the method allows reducing the load on the transmitting elements of the system.

This paper presents an approach to organize the group control underwater vehicles based on multi-loop adaptation algorithm of position-trajectory control system of moving object, with the estimating unmeasured parameters, reference model and contour that ensure astatism 2nd order. Estimation of unmeasured disturbances on the top control level as part of the reference model, which allows for highly accurate positioning of the final master AUV in the target point specified as a parameter to the reference model. The application of the developed algorithm expedient in control systems of moving objects group, where a single object from the leading group, and its parameters are used as the parameters of the reference model. The leading mobile object control system uses an adaptive control system with disturbance estimation. The control systems of the slave moving objects using positional-trajectory control system astatism second order, thereby providing high-precision tracking of the movement of the reference mobile object.

This paper presents an adaptive algorithm for position-trajectory control with reference model and estimation of nonlinear circuit unmeasured disturbances. The introduction of a robust observer derivatives in the base controller position-trajectory control, built on the principles of self-adjusting adaptive systems with a reference model, allows to estimate unmeasured disturbance characterized by non-linearity of the second order and higher, and to adapt the parameters of the system in order to reduce or minimize the zero mismatch errors between the control object and reference model. The use of derivatives allows the observer to increase the overall stability of the control system, otherwise, the system loses its stability in short-term effect of the disturbance on the control of high-order object.

The article discusses the the problem of controlling a synchronous generator, namely, maintaining the stability of the control object in the conditions of occurrence of noise and disturbances in the regulatory process. The model of a synchronous generator is represented by a system of differential equations of Park-Gorev, where state variables are computed relative to synchronously rotating d, q-axis. Management of synchronous generator is proposed to organize on the basis of the position-path control using algorithms to adapt with the reference model. Basic control law directed on the stabilizing indicators the frequency generated by the current and the required power level, which is achieved by controlling the mechanical torque on the shaft of the turbine and the value of the excitation voltage of the synchronous generator. Modification of the classic adaptation algorithm using the reference model, allowing to minimize the error of the reference regulation and the model under investigation within the prescribed limits, produced by means of the introduction of additional variables controller adaptation in the model. Сarried out the mathematical modeling of control provided influence on the studied model of continuous nonlinear and unmeasured the disturbance. Simulation results confirm the high level accuracy of tracking and adaptation investigated model with respect to the reference, and the present value of the loop error depends on parameters performance of regulator.

The paper considers the algorithms of position-trajectory control of mobile objects, are automatically distributed control forces and moments on the actuator. The basic control law is based on the equations of kinematics and dynamics and method of position-trajectory control of mobile objects. We consider the distribution of control forces and moments on the basis of pseudo-inverse matrix, which provides minimum MSE. This approach does not provide for preliminary separation of control channels, as is customary in classical systems of mobile objects. The proposed method is applied to the control system of aeronautical complex. The cases of excessive and insufficient number of control channels. The results of the simulation.
