This paper gives an overview of the theoretical basis of the norm optimal approach to iterative learning control followed by results that describe more recent work which has experimentally bench-marking the performance that can be achieved. The remainder of this paper then describes its actual application to a physical process and a very novel application(More)
— This paper shows a mixed sensitivity H∞ controller design, which uses the symmetric radio frequency system structure of a free electron laser. The controller design includes plant decoupling, which is needed for additional feedbacks. Furthermore unwanted additional resonant modes, so-called passband modes are suppressed. This paper shows a strategy by(More)
