A Stochastic Robustness Approach to Designing Unknown Input Observers for Non-Linear Systems

An Approach to Unknown Input Observation for Non-Input-Affine Nonlinear MIMO Systems

“…The developed observer was evaluated by Cheviron et al (2007) in a stochastic setting under the assumption of all states being available. Witczak et al (2007) presented an UI and state observer for a class of nonlinear discrete-time systems.…”
