2008 (English)In: International Conference on Computer-Aided Control Systems: [CACSD] ; San Antonio, TX, 3 - 5 September 2008, Piscataway, NJ: IEEE Communications Society, 2008, 371-376 p.Conference paper (Refereed)
The problem of estimating bounds for timevarying parameter perturbations using measurement data is addressed. In particular, time-varying time-delay is considered. An estimate of the perturbation is produced based on a quantized approximation of the uncertainty and the sparse structure of its derivative. The Pad´e-approximation and orthogonal collocation method are used to approximate the delay. A first-order system with time-delay is used as an illustrative example. The gain, time-constant and time-delay are considered as uncertainties here.
