Abstract :
This is Part II of a series of papers on the disturbance decoupling problem for linear constant coefficient descripror systems. In Part I necessary and sufficient conditions were determined that guarantee the existence of resulting closed loop system is regular, if possible of index less than or equal to one and the disturbance do not influence the input-output behavior of the system. In this paper we extend these results to the case that we also require that the closed loop system is stable. All results are proved based on condensed forms that can be computed using orthogonal matrix transformations, i.e., transformations that can be implemented as numerically backwards stable algorithms.
