Abstract

This paper present a new effective algorithm for the optimal realization of state estimate feedback controller structures for discrete time systems subject to finite-word-length constraints. The problem is formulated as a nonlinear programming to provide an easy and efficient optimization tool to solve such a complex problem. Simulation results of the optimum realizations of state estimate feedback controller structures are presented to illustrate the effectiveness of the proposed strategy
