The simulation and test of the formational flying was performed in the whole process of researches and developments of this satellite. Based on the improvement of traditional testing procedures, methods and techniques, a test method of formation configuration control base on TTDPN and AR((?)) model is presented. This paper researches the theory of T-Timed Discrete Petri Nets(TTDPN) and AR((?)) model and proposes a test sequence generation method based on the TTDPN and an online test data automatic interpretation method based on AR((?)) model. To prove the methods, a semi-physical real time simulation and test system based on the general cell is built. In this paper, the problems are solved, including simulation and test system modeling, generation of test sequences based on the simulation and test system models, processing and automatic interpretation of on-line test data, to shorten the test circle of the formation flying satellite, improved the reliability and reduce cost. Details are as follows:The basic theories of rapid test sequence generation method based on TTDPN and test data automatic interpretation method based on AR((?)) model are studied. First, the basic definition, operating rules and the matrix representation of the TTDPN theory are introduced and an example is provided. Then, definition of time sequence model, the identification and the parameter estimation method of AR((?)) model are introduced.Combined with the actual engineering requirements of a certain type of distributed In SAR satellite, the functions of the simulation test system is analyzed, the functional structure and general framework of the system is proposed, system software is designed, and a semi-physical real time simulation and test system based on the general cell is built eventually. The methods of rapid test sequence generation based on TTDPN and the method of automatic test data interpretation base on AR((?)) model were applied in the simulation and test system. The simulation and test system realized the rapid test sequence generation and online test data automatic interpretation of formation configuration control.To the problem of rapid test sequences generation, a rapid test sequence generation method based on the TTDPN model is proposed. First, the theory of TTDPN is used to set up TTDPN model for the simulation and test system. Then, test task is proposed based on the model. Finally, the algorithm of test sequences generation is used to test get test sequences for different test tasks.To the problem of online test data automatic interpretation, an test data automatic interpretation method based on AR((?)) model is proposed. First, the purpose of automatic interpretation of formation configuration parameters is expounded. Then, the features of formation configuration parameters are analyzed to prove the rationality of the assumptions and the feasibility of automatic interpretation method. Finally, the module of automatic interpretation method is built to prove the validity of the method by simulating and experimenting on the testing system.
