Abstract


Due to the rapid development of computer technology, the bus technology, control technology, network technology, computer cabin automation is becoming more and more widely used, especially in the exchange of information, the more prominent applications of real-time control and the control algorithm simulation field. With the rapid development of China's shipbuilding technology, field bus technology and configuration software-based network architecture has been able to achieve the the ship sailed process integration and automation, it can replace the engineer to properly implement the main and auxiliary equipment in the cabin and patrol management of the various subsystems, monitoring, and control. In this paper, the cabin automation network system established on the basis of mathematical modeling and control algorithm of the system of marine diesel engine was thorough and meticulous research. The variable universe fuzzy control and PID control systems for marine diesel engine characteristics, combining design variable universe fuzzy PID controller, and ship-based automation networks, set up a diesel engine the half physical network simulation platform and PC monitoring system to achieve the The actual operation of the system. First, MATLAB / SIMULINK software platform to establish the average model of a diesel engine, and the design of a control algorithm for the controlled object. According to traditional PID control, lack of speed control of marine diesel engine, designed based on variable universe fuzzy PID controller. The controller is not only to achieve a self-tuning PID parameters online, also improve the speed control performance of marine diesel engines. Simulation results show that the variable universe fuzzy PID controller overshoot in the system, there has been a marked improvement in the response time. The Advantech IPC MATLAB / RTW environment to establish a real-time simulation of diesel engine platform, the platform instead of the real object of the diesel engine. Access DSP controller, ANYCAN node and the entire cabin Ethernet-CAN network to build a diesel semi-physical network simulation system, the host computer using iFIX Software to achieve real-time monitoring of the health of the diesel engine system. Of this research work for the latter part of the real ship test and lay the foundation, more importantly, is an implementation of marine diesel engine speed control more advanced control strategy for future researchers to provide theoretical and technical support, to shorten the development cycle , will play an active role in promoting the development of marine diesel engine electronic control technology.
