What is it about?
In this article, a coupled observer to reconstruct an unknown input of a linear time invariant system is proposed. The feasibility is demonstrated by two examples, an academic one and a real biohydrogen production process.

Why is it important?
The proposed strategy for reconstructing an unknown input is relatively easy to implement in real cases.
Perspectives
The main idea of writing this article is to propose a straightforward strategy to reconstruct unknown inputs for fault detection and model-based optimization of real processes. The strategy was designed for a real biotechnological process with the formalism of control theory.
