| Abstract: | Based on the characters of the environment experimentation system,the application of gray model in status trend prediction of the experimental plants is studied.The key parameters are collected,and the feasibility of this trend prediction method is analyzed.The idea and method of the gray model in trend prediction of the environment experimental plants are provided.The air supply pressure of axletree during the temperature dropping and holding are taken respectively as the examples for validating the method.The collected data are calculated by Matlab,and the re-sults show that the prediction method is characterized by small amount data,simple calculation and accurate prediction.It is feasible to be used in trend prediction of the environment experimen-tation plants. |
