The Simulation Of Marine Main Diesel Remote Control System

In this paper, we simulate the marine diesel engine for linear mathematical models and remote control system, the main work is as follows:(1) In this paper, we analyze the modeling of ship diesel engine completely and establish the predilection for diesel mathematical model based the MAN B & W large low-speed diesel engine for the parent type. What we analyze including the composition, the working principle of the diesel engine speed control system and the characteristics of the integration of diesel host object established the foundation to achieve the sample controller.(2) On the diesel engine speed control algorithm simulation studies, we describe the general principles of PID control and digital PID control algorithms in detail and research a large number of references on the basis of the host for the integration of ship diesel plant. We structure in the classic PID control points, respectively, join the anti-saturation algorithm and the integral separation algorithm. Finally, we simulate the improved algorithms which lead to the better results. Thus the traditional PID control algorithm has been improved.(3) Based on the principle of fuzzy control and aimed at wind and waves in bad weather when the speed of diesel hosts cyclical changes, we design the adaptive fuzzy PID controller. And then we analyze it and result design steps for the general type of controller. Finally we use the integration of the diesel model of the host control object to carry out simulation experiments respectively in normal weather conditions and rough weather. It resulted from the simulation analysis, whether in normal weather conditions or large waves that the adaptive fuzzy PID controller to control effect superior of the conventional PID controller. So the design of adaptive fuzzy PID controller is successful because of its good regulation, small overshoot, short settling time, good dynamic performance and strong anti-interference ability. The control mode in effect represents an important future development of intelligent controller.
