Abstract :
A one-parameter family of perturbations is considered for an uncertain singular system which is nominally regular, impulse-free and stable. Based on linear fractional transformations, two different approaches in the time-domain and the frequency-domain are provided to derive a closed form solution for the maximal bounds under which regularity, impulse-immunity and stability are robustly preserved. The approaches can be successfully applied to both continuous/discrete-time singular systems
