Abstract [en]

Optimal input design typically depends on the unknown system parameters that need to be identifed. In this paper we consider robust input design for resonant systems that may span over a large frequency band. The concept is to use classical D-optimal design combined with a robust excitation signal which guarantees the same estimate variance regardless of resonance frequency. Simulations show that the proposed signal has the desired properties.
