[Abstract]:In recent years, with the electric and electronic technology, the theory of AC speed regulation, the modern control theory, the development of the motor design and manufacturing technology, the electric propulsion technology has developed rapidly. The electric propulsion equipment is widely used in the ships of ice breaking ships, fishing boats and cruise ships. It is an important method for the research of electric propulsion technology to enter the simulation experiment through the land test device. First, the design of the control platform of the test device and the research of the simulation experiment have a good effect on the development of the electric propulsion technology. Based on the project of the "ship intelligent micro network and the electromagnetic propulsion laboratory" of Dalian Maritime University, the design and simulation experiment of the control platform are carried out.
On the basis of the principle analysis of the electric propulsion load simulation system, the overall design of the control platform is carried out. A load simulation scheme is proposed, which combines the configuration software WinCC with the simulation software Matlab by using OPC communication technology, and determines the speed of the actual ship propulsion system and the method of turning moment and zoom.
The design of human-computer interaction system is designed by using the configuration software WinCC and the graphics and text display technology. The design includes communication system, operation interface and so on. It realizes the function of process control, state display and monitoring and alarm on computer.
According to the principle of ship propulsion, the ship and propeller are considered as a whole and the propeller load simulation model is built under the environment of Matlab/Simulink development. The whole simulation model is composed of input and output module, propeller load calculation module and torque conversion module, which can output torque control according to the load characteristic of propeller according to real time speed. Instructions.
In view of the lack of relevant data about the four quadrant load characteristics of the actual ship propeller, the ship propeller parameters are designed by using the ship parameters and empirical formulas. According to the experimental results of the Wageningen B series of propeller pools, the feedforward neural network algorithm is used to predict the four quadrant characteristics of the designed propeller, and the load is determined. The propeller thrust coefficient and torque coefficient of the simulation model.
By using the control platform, the propeller load simulation experiment of the propeller under three typical operating conditions is carried out. The experimental results show that the operation of the control platform is stable and the load simulation is correct, and the load characteristic of the propeller can be simulated.
The designed control platform not only provides experimental environment for program demonstration, teaching, but also provides engineering reference for other types of mechanical load simulation.
