Abstract

A novel optimal Finite Word Length (FWL) controller design is proposed in the framework of @m theory. A computationally tractable close-loop stability measure with FWL implementation considerations of the controller is derived based on the @m theory, and the optimal FWL controller realizations are obtained by solving the resulting optimal FWL realization problem using linear matrix inequality techniques.
