Robust Input Design for Resonant Systems Under Limited A Priori Information
2012 (English)In: 16th IFAC Symposium on System Identification, IFAC , 2012, 1611-1616 p.Conference paper (Refereed)
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.
