The need of achieving always better performance in present and future tokamak devices has pushed plasma control to gain more and more importance in tokamak engineering. When high performance and robustness are required, it is essential to adopt a model-based approach to design a control system. In this paper we introduce the basics of plasma current, shape position control in tokamaks. As examp...

We propose a new method to segment 3D structures with competitive level sets driven by a shape model and fuzzy control. To this end, several contours evolve simultaneously toward previously defined targets. The main contribution of this paper is the original introduction of prior information provided by a shape model, which is used as an anatomical atlas, into a fuzzy decision system. The shape...

We consider minimal time and minimal norm of the optimal controls for a multi-dimensional internally controlled heat equation with control domain varying over a class of open sets. Twoproblems are formulated separately into different types of shape optimization problems over this open set class. The governing equation with any given initial value and admissible control are considered as constra...
