The article focuses on developing synthesis methods for automatic heading control systems for the rudder-controlled sea vessel. The solution of the problem of vessel heading control is carried out in the conditions of heavy sea. The disturbing effect of the external water environment causes the vessel yawning, which results in exceeding activity of the steering gear. This leads to its increased wear and loss in the longitudinal speed of the vessel. To reduce the wave effect there has been supposed an approach based on the additionally introduced internal model of the ship dynamics. The given approach is aimed at improving the operation of the steering gear in rough seas. To implement the proposed algorithm, changes are made to the original system by introducing an internal model in parallel to the control object and modifying the feedback channel of the control system. To describe the sea vessel dynamics there is used the 1st order Nomoto model, the steering gear model is implemented in accordance with the imposed speed limits and the rudder shift value. Wave disturbance is close to harmonic disturbance. The identification of the parameters of the internal model can be carried out in advance, both by maneuvering tests and by the process of operation. Numerical simulations carried out in the MATLAB/Simulink system confirmed the advantage of the proposed approach. The synthesis of control in a system with an internal model makes it possible to significantly neutralize the influence of wave disturbance. The modifications introduced to the original control system help to improve functioning of the steering gear, significantly reducing the number of rudder shifts during operation.

This paper describes a logical model applied as a soft control tool to mobile objects. The model of the logical spatial situation without uncertainty, i.e., according to the law of excluded middle, is considered as the basis. Nonetheless, the motion rules are derived using an approach applied in constructible mathematics and logic. The approach consists in the finitude of variants of control and analyzing all potential traffic scenarios. The constructible object considered in this paper is the situation’s logical model. The constructible approach consists in considering the model of a typical railway station by the example of which the traffic is analyzed. The situation’s logical model is implemented as a condition for potential traffic. This model is described using mathematical logic with the help of logical variables and rules. The control system in this case makes use of permissible versions of logical designs. The control relies on the feasibility of traffic. The system of control rules is developed on the basis of the logical situation’s model and formed without uncertainty. The article provides an analysis of complementary kinds of traffic.

Abstract Aiming at the problem of mechanized and repeated parts grasping, and aiming to reduce the development cost, this study added an end-effector and designed a ROS-based grasping robot control system on the basis of fully analyzing the structure and workflow of the robot. The grasping robot can be controlled and monitored in real time by operating on the RVIZ interface. According to the needs and process of grasping work, the control system process design and control system programming of the robot are completed. Subsequent simulation experiments and real object control experiments show that the control system has high robustness and real-time performance. The control system can meet the task of mechanization and repeated parts grasping, and can effectively improve the production efficiency, enhance the competitiveness of enterprises, and reduce the cost of enterprises.

Method of synthesis of a control system for the object with the distributed parametres, providing compensation of dynamic properties of the object and giving to it of properties of standard model of a set. The system possesses the property of an adaptability to parametrical interference of the object. Control along the unobservable coordinate of the object is implemented by synthesizing a chain structure that implements a transfer function close to the inverse transfer function of the object. Weak sensitivity to parametric instability is provided by solving the inverse problem of dynamics. As an example, the heating of a massive billet in a convection oven is considered.
