Abstract

This paper analyzes the performance of digital linear regulators which use finite-precision logarithmic arithmetic. A linear equation is derived which describes the steady-state covariance matrix of such a closed-loop regulator system. The utility of this covariance matrix in designing regulators which use logarithmic arithmetic is illustrated through several numerical examples and the presentation of a regulator design methodology.
