Sliding mode controllers are long-recognized for their robustness features against plant uncertainties and unmodeled dynamics. Recently, the interest emerged to extensions of these algorithms to distributed parameter systems. Motivated by modern control applications, standard first- and second-order sliding mode control algorithms are presented in the infinite-dimensional setting and their attractive features are discussed for distributed and boundary control of PDEs. The backstepping method is additionally invoked for boundary stabilization of unstable coupled parabolic linear PDEs. A special attention is paid to the underactuated case of 2 coupled reaction-diffusion processes controlled by a scalar boundary input only.

Consensus pertains to the case in which a network of systems synchronise their behaviour and reach a common behaviour. In the case of heterogeneous networks, in which systems may have different parameters and even different dynamics, the consensus problem must be addressed through a general framework which takes into account the type of interconnection, the individual agents' dynamics, the network topology and the strength of the interconnection. Motivated by synchronization paradigms appearing in the realm of neurosciences, we present a general framework of analysis of heterogeneous networks of dynamical systems with nontrivial dynamics. The framework build upon the essential observation that the network behaviour may be decomposed in two parts: on one hand, we exhibit the existence of what we call {emergent dynamics} and, on the other, the synchronisation-erros dynamics. These form two dynamical systems whose trajectories evolve in orthogonal spaces. Then, we use stability theory to study the behaviour of each system: under the assumption that the emergent dynamics has a stable attractor we show that problem of analysis of the network behaviour may be formulated as a dual problem of stability of such attractor and the stability of a synchronisation manifold. As illustration, we broach particular cases of Stuart-Landau oscillators and networks of Hindmarsh-Rose neurons. The talk is wrapped up with a brief discussion of open problems on synchronisation of heterogeneous networks in various areas, including social networks, neurosciences, electricity-distribution networks.

we will present recent researches on event-based continuous control. This type of control consist in updating the control only « when needed » instead of periodically as usual. Despite some drawbacks, event-based control seems to be very advantageous in terms of computation and network cost. The birth and the main ideas for this type of approach will be given and practical physical applications where this type of approach seems to be promising will presented.

The aim of this talk is to present the application of the control theory to the stochastic differential equations. This class of the systems are described by Itô stochastic differential equations whose diffusion is controlled by noises which are multiplied with the state vector or with a function of the state vector. These noises are Wiener processes, also know as Brownian motions. In this talk, the following items are treated : Itô process and Itô formula, existence and uniqueness for the solution of a stochastic differential equation, stability notions for stochastic processes (with Lyapunov approach), differential-algebraic equations, time-delays.
