Abstract :
The application of a supervisory system identification scheme for flexible structures is considered in this article. The method is based upon quantifying parameterized models which interpolate partial impulse response sequences. This approach always produces a stable system function for rational models, and both minimum phase and nonminimum phase systems are admissible. A supervisory scheme eliminates some of the attainable models through a comparison of their DC-gains, and further reduces the order of the identified system by neglecting the near pole/zero cancellations in regions close to the origin of the unit disk, or with negative real z values. A review of this technique as it applies to flexible structures, and applications of this algorithm to flexible structures are presented
