Abstract

Optimal input design typically depends on the unknown system parameters that need to be identified. 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.

Conference

Conference	16th IFAC Symposium on System Identification (Sysid 2012)
Abbreviated title	Sysid 2012
Country	Belgium
City	Brussels
Period	11/07/12 → 13/07/12
Other	The scope of the symposium covers all major aspects of system identification, experimental modelling, signal processing and adaptive control, ranging from theoretical, methodological and scientific developments to a large variety of application areas. To enhance the applications and industrial perspective of the symposium, participation by authors from industry is particularly encouraged. It is the intention of the organizers to promote SYSID 2012 as a meeting place where scientists and engineers from several research communities can meet to discuss issues related to these areas.
