%R 10.1109/CDC.2011.6161334 %B Proceedings of the 50th IEEE Conference on Decision and Control and European Control Conference (CDC-ECC) %X A fast implementation of a given predictive controller for nonlinear systems is introduced through a piecewise constant approximate function defined over an hyper-cube partition of the system state space. Such a state partition is obtained by maximizing the hyper-cube volumes in order to guarantee, besides stability, an a priori fixed trajectory error as well as input and state constraints satisfaction. The presented approximation procedure is achieved by solving a set of nonconvex polynomial optimization problems, whose approximate solutions are computed by means of semidefinite relaxation techniques for semialgebraic problems. %D 2011 %L eprints2444 %A Massimo Canale %A Vito Cerone %A Dario Piga %A Diego Regruto %K Aerospace electronics; Approximation algorithms; Function approximation; Optimization; Polynomials; Trajectory %I IEEE %O 50th IEEE Conference on Decision and Control and European Control Conference (CDC-ECC), held in Orlando USA), December 12-15, 2011 %T Fast implementation of model predictive control with guaranteed performance %P 3375-3380
