✦ Synopsis

The compensating problem for forward-backward periodic systems in discrete-time has been studied. A normal compensator for this kind of systems is proposed using a suitable observer. In addition, some properties to construct the periodic observer and compensator can be obtained from the associated invariant systems.

In this paper, we give a numerically reliable algorithm to compute the zeros of a periodic descriptor system. The algorithm is a variant of the staircase algorithm applied to the system pencil of an equivalent lifted time-invariant state-space system and extracts a low-order pencil which contains th
