Constructing sparse realizations of finite-precision digital controllers based on a closed-loop stability related measure
We present a study of the finite word length (FWL) implementation for digital controller structures with sparseness consideration. A new closed-loop stability related measure is derived, taking into account the number of trivial elements in a controller realization. A practical design procedure is p...

| 520 | |a We present a study of the finite word length (FWL) implementation for digital controller structures with sparseness consideration. A new closed-loop stability related measure is derived, taking into account the number of trivial elements in a controller realization. A practical design procedure is presented, which first obtains a controller realization that maximizes a lower bound of the proposed measure, and then uses a stepwise algorithm to make the realization sparse. Simulation results show that the proposed design procedure yields computationally efficient controller realizations with enhanced FWL closed-loop stability performance. | ||
