• fault isolation observers
• robust fault isolation
• non-interacting control

This paper presents a method to design dynamically extended fault isolation observers (FIOs). Therefore, a design procedure for dynamic non-interacting controllers is proposed. Based on the duality between non-interacting control and observer-based fault isolation a technique to design dynamic FIOs is deduced, which provides additional degrees of freedom compared to static FIOs. These are employed in this article to increase robustness with respect to high-frequency disturbances.
