Abstract

This paper present a new effective algorithm for the optimal realization of digital controller structures using the delta operator for sampled data systems subject to Finite-Word-Length (FWL) constraints. The problem is formulated as a non-linear programming to provide an easy and efficient optimization tool to solve such complex problem. Simulation results of the optimum realizations of digital controller structures are presented to illustrate the effectiveness of the proposed strategy.
