Sensitivity to high-frequency measurement noise of nonlinear high-gain observers

Authors: D. Astolfi, L. Marconi, L. Praly, A. Teel, NOLCOS 2016, 10th IFAC Symposium on Nonlinear Control Systems, pp. 874 - 878, August 23-25, 2016, Monterey. DOI: 10.1016/j.ifacol.2016.10.274
This paper deals with the characterisation of the sensitivity to high-frequency measurement noise of nonlinear high-gain observers. The proposed tool provides bounds for the steady-state estimate in presence of noise when the high-gain parameter characterising the speed of convergence of the observer is fixed. The nonlinear analysis captures the effect of the noise frequency showing the “low-pass” filtering properties of the observer.
