Abstract
We discuss a numerically stable algorithm, originally proposed in [3], that competes a. regularizing output feedback for descriptor systems. In [3] th e system is transformed to a condensed form via a sequence of singular valu e decompositions (SVDs). We show that the expensive SVDs can be replaced by reliable, more efficient orthogonal decompositions. Moreover, we demonstra te how the feedback is obtained from our slightly different condensed form.
