Subject

Control of hybrid and switched systems
Combining continuous- and discrete time analysis and design techniques for systems that evolve continuously but also undergo instantaneous changes.

Interconnection of hybrid systems
Interconnection of hybrid systems (G, GJ) and (K, KJ).

Distributed control
Scalable analysis and design approaches for large networks of systems.

Cyclic interconnected systems
Cyclic interconnected systems.

Robust control
Analysis and synthesis techniques for linear systems affected by uncertainties.

Robust vs nominal design
Robust (left) vs nominal (right) design for an uncertain hybrid system. (Top) reference tracking and (bottom) control effort.

Linear matrix inequalities and integral quadratic constraints
Exploring the applicability of linear matrix inequalities and dynamic integral quadratic constraints in control oriented problems.
