Abstract :
A new Generalized Predictive Control algorithm in a decentralized controller framework is presented. Using a new formulation of output end-point weightings the nominal stability is guaranteed. Robust stability with respect to additive plant uncertainty is assured by an IMC scheme. Using the method of finite elements and a description of composite subsystems respectively the dynamical behavior in the heating area of the crystal furnace TITUS is modeled. A final simulation depicts to a more accurate temperature gradient tracking.
