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.

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.

Testing and debugging of real equipment is a time consuming task. In particular, in the case of marine robots, it is necessary each time to carry out the transportation and deployment of a robot on the water. Experiments with not yet fully functional prototype of marine robot equipped with expensive hardware is in the meantime very risky. Therefore, the use of simulators is affordable way to accelerate the development of robotic systems from the viewpoint of labor effort and cost of experiments. This paper presents a simulator specifically designed for autonomous unmanned underwater vehicles.
