| Abstract: | Test data of governor control characteristics for 4125A diesel engine was processed through Matlab.Initial tracing spot diagram was obtained through tracing method based on mathematical model,and integrity graph was drawn by least square polynomial fitting.Graphs were contrasted before and after curve fitting,therefore precision and reliability of data processing and polynomial fitting with Matlab proposed this paper was feasible. |
