В современных высших гражданских и военных учебных заведениях при изучении систем управления и навигации используются тренажеры, построенные по следующему принципу: промышленный пульт управления (система управления), устанавливаемый на отечественных судовых системах, соединяется со схемой или устройством, моделирующем поведение объекта управления. Такие тренажеры зачастую дороги, сложны в изготовлении, обслуживании и наладке. При современном уровне развития вычислительной техники в обучении различным технологическим навыкам и умениям все чаще используются программы-тренажеры, с достаточно большой точностью моделирующие как систему управления, так и объект управления. В статье предлагается программный тренажер, позволяющий моделировать различные режимы движения судна на подводных крыльях, включая аварийные режимы движения, посредством отображения на дисплее компьютера пульта управления движением судна на подводных крыльях с возможностью изменения заданных значений кинематических параметров. В рассматриваемом тренажере предусмотрена возможность отображения процесса движения судна в продольной и поперечной плоскостях, а также графиков изменения во времени соответствующих параметров состояния судна. Приводятся видеокадры представленной программной оболочки. Обсуждаются преимущества использования предложенного программного продукта в качестве тренажера для обучения судоводителей. В статье представлен один из возможных вариантов программного обеспечения для тренажера управления движением судна на подводных крыльях. Для создания тренажера в данной работе была выбрана система Бирюза 2 , предназначенная для установки на пассажирских судах на подводных крыльях Циклон , Альбатрос и Колхида для повышения их маневренных и мореходных качеств. In modern higher civil and military educational institutions, when studying control and navigation systems, simulators are used based on the following principle: an industrial control panel (control system) installed on domestic ship systems is connected to a circuit or device that simulates the behavior of the control object. Such simulators are often expensive, difficult to manufacture, maintain and set up. At the current level of development of computer technology, training in various technological skills and abilities is increasingly used simulator programs that simulate both the control system and the control object with a fairly high accuracy. The article offers a software simulator that allows you to simulate various modes of movement of a hydrofoil vessel, including emergency modes of movement, by displaying a computer control panel for the movement of a hydrofoil vessel with the ability to change the set values of kinematic parameters. In this simulator, it is possible to display the process of ship movement in the longitudinal and transverse planes, as well as graphs of changes in time of the corresponding parameters of the ships condition. Video frames of the presented software shell are provided. The advantages of using the proposed software product as a simulator for training skippers are discussed. The article presents one of the possible software options for the hydrofoil motion control simulator. To create a simulator, the system Biryuza 2 was selected in this work. It is intended for installation on passenger hydrofoils Cyclone , Albatros and Kolhida to improve their maneuverability and seaworthiness.

The novel FPGA (Field Programmable Gate Arrays) can embed a processor to be an SoPC (System-on-a-Programmable-Chip) environment which allows user to design the applications by mixing hardware and software. Therefore, a motion control system of wafer-handling robot based on the SoPC technology is presented in this paper. In FPGA, it is consists of two modules. The first module is Nios II processor which is used to realize the motion trajectory planning and three-axis position/speed controllers by software. The program developed in Nios II processor uses C language. The second module is presented to implement three-axis current vector controllers by hardware, and VHDL (VHSIC Hardware Description Language) is applied to describe the controller behavior. Therefore, a fully digital motion controller for wafer-handling robot, such as three current vector controllers, three position/speed controller and one trajectory planning are all can implemented by a single FPGA chip. Finally, an experimental system constructed by an FPGA experimental board, one three-DOF wafer-handling robot, and three inverters is set up to demonstrate the correctness and effectiveness of the proposed SoPC-based motion control system of wafer-handling robot.

The ITER (International Thermonuclear Experimental Reactor) is an international collaborative project, and its object is aiming at demonstrating the scientific and technological feasibility of fusion energy for peaceful purposes. In the ITER, the four important engineering challenges are the first wall of the blank model, the remote handling (RH), the heating of the plasma, and the superconducting technology. The RH control system is very complexity, and the total number of the control nodes is 15378, which consists of the control nodes in the Tokamak equipment, the hot cell equipment and the control room equipment. Only the number of the control nodes of the transfer cask system (TCS) is up to 2580. The TCS is one sub system of ITER RH system, which provides the means for the remote transfer of (clean/activated/contaminated) in-vessel components and remote handling equipment between hot cell facility and vacuum vessel through dedicated galleries and lift in the ITER buildings. Due to the experimental facility with a very long timeline, the control software on the ITER is better suited using an open source solution as compared to a commercial solution. According to market share and proven record, command control and data acquisition and communication (CODAC) group chooses the EPICS (Experimental Physics and Industrial Control System) as the preferred solution. China takes part in the ITER, and wishes to grasp the RH technology, which is one of the four key technologies related to the future fusion reactors for electric power generation. According to the CODAC system configuration with EPICS component, the concept control architecture of the TCS is presented in this paper. The control system consists of the file network, the interlock network, the safety network, real-time network, RH control network and visual supervising network etc. Then, the paper analyses each part corresponding requirement function. As a result, a development service platform concept is set up. Finally, the experiment system of the leg of the TCS has been constructed.
