Optimal Fwl Design of State - Space Digital Systems with Weighted Sensitivity Lminimization - - - - and Sparseness Consideration
نویسنده
چکیده
The optimal Finite Word Length (FWL) state-space digital system design problem is investigated. It is argued that it may be desirable to minimize a frequency weighted sensitivity measure over all similarity transformations. The set of optimal realizations minimizing this weighted sensitivity is completely characterized. It is shown that a subset of the optimal realization set consists of sparse Schur realizations. Some nice properties of the Schur realizations are discussed.

متن کاملTwo approaches based on pole sensitivity and stability radius measures for finite precision digital controller realizations
This paper compares the two approaches based on pole sensitivity and the complex stability radius measures, respectively, for optimizing the closed-loop stability robustness of digital controllers with respect to &nite word length (FWL) errors in &xed-point implementation. Design details and related optimization procedures are derived for the two methods. The two measures, although derived from...

This paper considers the problem of synthesizing the finite-word-length (FWL) two-dimensional (2-D) state-space filter structures with minimum weighted sensitivity. Two kinds of frequency-weighted sensitivity measures, one based on a mixture of L1=L2 norms and the other a pure L2 norm, are defined in place of the usual sensitivity measure and an upper bound expressed in terms of 2-D weighted Gr...

Ahtract-In this paper, we present a s tudy on the Finite Word Length (FWL) implementation of digital controller structures. The relevant FWL closed-loop stability related measures are investigated, and a n algorithm is provided to search for the sparse controller realization that yields a computationally efficient structure with good FWL closed-loop stability performance. A numerical example is...
