The POD propulsion ship is a new type of electric propulsion ship. Due to its special structure, the course control problem is complicated. The application of neural network in control field is more and more extensive. In this paper, based on POD ship's structure, MMG separated ship model has been established, and a CMAC-ADRC integrated controller is designed by combining the advantages of active...
For a long time, ship motion and main engine propulsion system are controlled independently. Few scholars have focused on the comprehensive study of both. Moreover, there are no effective simulation platform for the integrated control. Therefore, according to the real ship bridge configuration, combining with the software simulation technology and the idea of hardware in loop simulation, the article...
The purpose of the paper is to develop a novel simulation system for ship propulsion plant. The nonlinear mathematical model of main propulsion system of a large container ship is established, consisting of the large low speed two-stroke diesel engine, shaft, fixed pitch propeller and ship hull dynamics. What's more, a new full mission ship diesel main propulsion plant remote simulation system, including...
By using the quasi steady state and mixed modeling methods, the nonlinear mathematical model of the ship main propulsion system is established. An improved integrated control algorithm based on CMAC and PID is presented in the ship propulsion system. Simulation computing is completed to investigate the dynamic characteristics of the ship propulsion system on rough sea conditions. The results show...
Taking the main engine and propulsion system of the large-scale container ships as the controlled object, a type of main engine remote control simulation system is designed, using the CAN-bus and database administration technology as well as touch-screen equipments. The system is composed of ECR controls system, BCR control system, and local control system with high density of integration. It can...
Based on the modeling method of the co-operation between the characteristic maps and the mathematical equations, a propulsion system simulation model which includes model for large low speed two-stroke diesel engine (MAN B&W 10L90MC) and model for shaft, propeller and ship hull dynamics is proposed. To calculate propeller's characteristic, the regression functions are adopted. The simulation experiments...
At present, most of marine engine room simulators (MERS) in the world are based on networking technology. But such MERS needs much money and large space to install and use. So it can not meet the demand of the training individually in spare time for the crew. So a simulation system of a PC-Based marine diesel engine has been proposed. In this paper, a quasi steady state model of a large low-speed...
A type of intelligence PID controller based on BP neural network is proposed. That the robust intelligence PID controller contains three-layer fuzzy neural network is simple in structure and steady in work. The PID parameters can be self-adjusted according to the system model and can be automatically tuned via neural networks weights. This controller is used in marine engine propulsion system to control...
