Description
Technical Field
The invention relates to a semi-physical simulation device and a semi-physical simulation method, in particular to a ship power semi-physical simulation device and a ship power semi-physical simulation method.
Background
With the gradual decline of global oil reserves and the tightening of global emission regulations, green traffic is becoming a great trend. At present, the development direction of the automobile industry is inclining from a fuel vehicle to a hybrid vehicle and a new energy vehicle, and the automobile is gradually greened. In the ship industry, many shippers seek a novel power mode with low modification cost, low operation cost and low maintenance cost. However, the actual effect of the novel power mode cannot be predicted without testing and debugging, so that experiments are required to verify the reliability of the novel power mode.
However, the full physical test of directly performing the combined test run on the system not only has the problems of high cost and high risk, but also increases the risk of damaging and controlling the system. Therefore, the simulation technology can be used for reducing the test risk, saving the cost and improving the test efficiency. Currently, common simulation techniques are mainly classified into digital simulation, semi-physical simulation and physical simulation. Digital simulation is the process of abstracting system characteristics by using mathematical means and carrying out experimental research and verification on a mathematical model on a computer. Semi-physical simulation is the process of building mathematical models, such as control models, for some parts of a research system, replacing some parts with physical or physical models, and connecting them to form a simulation loop for testing. Physical simulation is the process of testing the research system by using all physical models or objects and connecting them to form a simulation loop. In mathematical simulation, part of the system is difficult to accurately model, and noise and other interference are ignored in the simulation, so that the accuracy is not high. In pure physical simulation, a lot of work and test equipment are carried out before actual test, but a large amount of equipment manufacturing, installation, debugging and other work are required, the structure is complex, the manufacturing cost is high, the model is difficult to reuse, and the universality is not strong. The semi-physical simulation avoids the problems of high cost and poor universality in the physical simulation, is closer to reality than the digital simulation, has high simulation confidence coefficient, and is increasingly applied in the development process of a control system.
