• Observer-based fault isolation
• robust fault isolation
• parametric eigenstructure assignment
• uncertain systems

This paper presents a design for fault isolation observers for linear uncertain systems. It is based on a parametric eigenstructure assignment technique, which gives a comprehensive interpretation of the arising degrees of freedom in non-square systems with more linearly independent measurements than potential faults. These degrees of freedom are employed to fulfill the structural constraints of fault isolation as well as possible with respect to different optimization criteria. Therewith, robustness with respect to uncertain parameters is increased.
