  • Control of distributed underwater robot systems using reference adaptive model

    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.

  • Estimation of nonlinear higher order disturbances in the adaptive algorithms for position-trajectory control

    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 Basic Algorithm of Adaptive Management of the Synchronous Generator with a Reference Model

    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.

  • Algorithms multiconnection position-trajectory control of mobile objects

    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.

  • Position-Trajectory System of Direct Adaptive Control Marine Autonomous Vehicles

    From the point of view of development of control systems, a significant disadvantage of indirect adaptive control systems of moving objects is the fact that the limiting the properties of such system are determined by the basic adaptive regulator. In other words, to solve the problem of adaptive control it is required to find a non-adaptive regulator, which solves the problem of marine autonomous vehicles. In this case, the adaptive controller replaces many controllers that solve the control of multiple objects in a non-adaptive domain. The paper presents method of direct adaptive control for marine autonomous vehicles. Nonlinear mathematical models are considered. The method is based on position-trajectory control approach. It is proved the designed by suggested method controller is a vector nonlinear PI-regulator. The regulator ensures asymptotical stability of the closed-loop control system.
