Abstract: On the basis of study on optimal input signal design, data compatibility checking and data analysis, the corresponding softwares were prepared by way of the software engineering method, and then controlled by the managing software. So, an integral state estimation and parameter identification software package for military aircraft MASEPI was formed. Finally, the efficiency and practicality of the software package were confirmed by simulating, test and flight test data processing. The state estimation and parameter identification software package for military aircraft MASEPI was applied to the practical engineering of test and flight test data processing. This paper is a brief introduction to the development of the above mentioned state estimation and parameter identification software package MASEPI.

Key words: state etimation and parameter identification, test and flight test data processing, software package, software engineering
