Design of sparse digital finite-precision controller structures based on an improved closed-loop stability related measure
An improved closed-loop stability related measure is derived for digital controller structures with finite-word-length (FWL) implementation, which takes into account the number of trivial elements in a controller realization. A practical design procedure is presented to design sparse controller realizations with good FWL closed-loop stability characteristics. A case study shows that the proposed design procedure yields computationally efficient controller realizations with enhanced FWL closed-loop stability performance.

Abstract
An improved closed-loop stability related measure is derived for digital controller structures with finite-word-length (FWL) implementation, which takes into account the number of trivial elements in a controller realization. A practical design procedure is presented to design sparse controller realizations with good FWL closed-loop stability characteristics. A case study shows that the proposed design procedure yields computationally efficient controller realizations with enhanced FWL closed-loop stability performance.
