DESCRIPTION:Georg Bock\nNMPC - Nonlinear Model Predictive Control - is pro
 bably one of today’s most promising model-based approaches to deal with 
 nonlinear processes under uncertainties. Its simple but challenging idea i
 s to use detailed nonlinear dynamical models to predict the performance of
  the process to be controlled over a sufficiently long time horizon. In th
 e omnipresence of per-turbations and model-plant mismatch\, an optimal con
 trol law must then be repeatedly com-puted online\, which ensures that the
  economic and/or tracking performance of the process is optimized subject 
 to all kinds of important restrictions.\nHowever\, even the fastest "all-a
 t-once" optimization solvers available today are much too slow to compute 
 an optimal control quick enough to be used in very fast and/or very comple
 x processes with correspondingly complex models\, as they are frequently m
 et\, e.g.\, in produc-tion processes or in vehicle dynamics.\nThe lecture 
 will review some basic concepts of NMPC including theoretical results show
 ing that global stability can be achieved by economic performance criteria
 . It will then outline some of the ideas behind the new so called “multi
 -level real-time iterations” and “online ac-tive set” optimization a
 lgorithms that have produced a speed-up by 4 – 5 orders of magnitude ove
 r earlier approaches to NMPC. Extensions to mixed-integer optimal control 
 will be sketched.\nThe performance of the new methods will be demonstrated
  - with the support of some videos - by engineering applications such as d
 istillation processes\, wind power generating kites\, and energy conservat
 ion in heavy duty trucks.
