✦ Synopsis

This paper deals with an identification package. In the first part, the various classical off-line parameter estimation methods implemented are described. A graphic editor allows one to prepare the input-output data easily, which ensures a correct estimation. However, good methods and robust algorithms are not sufficient to guarantee a successful use of identification in industry. Another necessary component is the know-how of the person carrying it out. In the second part, the expert system SEXI ("Syst~me EXpert en Identification") is considered, which uses the software mentioned above so as to determine the model structure. SEXI behaves as a supervisor: it selects and runs the appropriate numerical module to obtain the quantitative results necessary for its reasoning and it iterates this process until a relevant model is found.
