Robust observer design for discrete-time locally one-sided Lipschitz systems'

摘要

The robust estimation of discrete-time one-sided Lipschitz systems is considered. A linear matrix inequality based approach is presented to design a nonlinear state observer such that the input-to-state stability of the estimation error is locally guaranteed while minimizing an upper-bound on the l(infinity)-induced system norm from the disturbance input to the error system performance output. The effectiveness of the approach is demonstrated in simulation for several numerical examples. (C) 2019 European Control Association. Published by Elsevier Ltd. All rights reserved.
