Abstract :
Frequency response analysis is a classical method for obtaining models of linear, time-invariant systems. However, the quality of the results strongly depends on the experiment design and choice of parameters. Likewise, different problems may demand a fault diagnosis. This article presents a knowledge-based system that guides the user through the planning and execution of a frequency response experiment, and it also performs a fault diagnosis and suggests remedies for possible problems.<>
