Learning outcomes

At the end of the course, the students know the main notions of control theory for ordinary differential equations , i.e., controllability, observability, bang-bang controllers, the notion of cost function and optimal control, the Pontryagin maximum principle.They know also the basic notion of strongly continuous semigroup of linear operators together with the one of evolution equations, basic for future applications to partial differential equations and related control problems, of very large interest in various applied sciences.

Teaching methods

The course is structured in lessons in a room, where there are described the basic elements of control theory for ordinary differential equations. The first aspect concern differential equation in finite-dimensional space. In a second time semi groups of linear operators in Banach spaces are introduced and this allows to present infinite dimensional control theory. At the end of the course students can follow the most recent development on control of dynamical systems.

Assessment methods

Assessment methods consists in an oral examination that wants to establish the achievement of the knowledge required by the program of the course. The prove has the further aim to verify the degree of knowledge of the main concepts of the matter.
