A Study On The Application Of Artificial Intelligence In Direct Torque Control

The integrated bridge systen (IBS), which uses the system designing method, combines a variety of navigation, control operation and radar collision avoidance equipment. It is using computers; modern control and information processing technology to achieve the ship automation, on behalf of the trends of modern equipments on the ships.Now, the electronic devices on the ships are based on the serial interface protocol to exchange information in accordance with NEMA0183 which has shortcomings about a low transmission rate, complex line, multi-node and reliability. While the fieldbus technology (CAN) makes up for these shortcoming because of its high anti-interference ability and high communication speed.So it has been widely applied to automotive electronics,but has not received a good application in the data communications on the ships. This article focuses on analysis of these problems and disadvantages and communication systems to address of the proposed use of field bus (CAN) communication system for a new ship design, and is involved in the development of small-scale tests on the bridge system, and tests on the small-scale bridge system.The designed CAN of the system is convenient, practical, economic, and anti-jamming.By thorough analysis and synthetize the technical theory and technical regulation of CAN BUS, propose data automation control system of the ship based on CAN protocol. the paper analyzes the design requirements of Ship Data Communication Automation System.Focusing on the core controller, the paper describes the design with two aspects of hardware and software in detail. This paper chooses dsPIC30F4011 as control chip and designed hardware circuits and software programs. With the core of the dsPIC30F MCU, the controller communicates the data with the magnetic compass, azimuth digital instrument, GPS and other navigation equipments through CAN Field Bus; the controller achieves a comprehensive ship-to information showing through switching the LCD menu by the buttons.Meanwhile, in view NEMA0183 interfaces the node transceiver to achieve protocol conversion. These nodes transponder control modules sent data to CAN bus to communicate with the central control module. The users can use man-machine interface to receive data, through the CAN bus send information back to the various data control nodes. The follow text gives the related hardware block diagram and flowchart.using CAN technology to convert the system of Small-scale communication bridge subsystem and achieve a new structure of CAN bridge system. The system master controller with the PC as the core, through the integrated system developed for digital magnetic compass, digital azimuth instrument, GPS, solar azimuth instrument and joystick consoles and other digital devices that can accurately measure the ship's course, side angle , roll angle, pitch angle and the target true position and other information, with automatic calibration, automatic measurement and calculation of the remaining deviation to amend the magnetic variation of the function; can form directly to the wheel dynamic display phase data, meanwhile send data to the radar, autopilots and so on.The results show that CAN bus technology has outstanding reliability, real-time and flexibility is applicable to data communication systems'building of the ship, it raises a new idea of ship communication systems'development.
