Combined nonlinear model reduction and multiparametric nonlinear programming for nonlinear model predictive control

摘要

This work presents a methodology which combines nonlinear model reduction techniques with recent advances in multiparametric nonlinear programming (mp-NLP) to derive explicit multiparametric controllers for nonlinear MPC (NMPC). Nonlinear model order reduction (NMOR) techniques based on empirical gramians are used for the model reduction step. The approach is illustrated on a 32 states distillation column model example.
