摘要：This article presents a robust estimation strategy to reconstruct unknown inputs for nonlinear systems. The observer proposed consists of a Luenberger observer, which estimates the internal states of the system, coupled to a super-twisting observer, which reconstructs the unknown input considering the precedent estimations. The feasibility of the strategy is demonstrated for a real biohydrogen production process.
