Abstract
The paper addresses the problem of characterizing and computing an estimation of the basin of attraction for saturated hybrid systems. Hybrid systems presenting saturation on signals involved in both the continuous-time and the discrete-time dynamics are considered. A geometrical characterization of local convergence is provided and employed to extend results proper of continuous-time and discrete-time saturated systems to the hybrid ones. A computation oriented condition of local convergence is given in form of convex constraints.

Abstract
This paper presents a criterion to characterize control invariant polytopes for differential inclusion systems. The practice-oriented method, based on viability theory and convex analysis, can be applied to determine computational procedures to obtain families of control invariant polytopes. The criterion is based on a necessary and sufficient condition for viability to hold at any point on the boundary of a polytope.

Abstract
This paper proposes an anti-windup strategy to deal with stability and performance requirements for a class of hybrid systems, such as those including a reset controller and subject to input saturation. The computation of the anti-windup compensator aiming at ensuring both $\mathcal{L}_2$ input-to-state stability and internal stability of the closed-loop system is carried out from the solution of matrix inequalities. Depending on the way chosen to describe reset rules, the conditions for designing the anti-windup compensator are expressed through nonlinear matrix inequalities or linear matrix inequalities. Some optimization criteria in both cases are considered for the synthesis purpose: maximization of the $\mathcal{L}_2$-norm upper bound on the admissible disturbances for which the trajectories are assured to be bounded; minimization of the $\mathcal{L}_2$-gain of the disturbance to the system to-be-controlled output; and the maximization of an estimate of the domain of attraction of the origin.

Abstract
This paper addresses the problem of stability analysis for a given class of nonlinear systems resulting from the connection of a linear system with an isolated backlash operator. Constructive conditions based on LMIs to ensure closed-loop stability are proposed by using some suitable Lyapunov functionals with quadratic terms and Lure type terms, and generalized sector conditions. Additionally, the boundary of the associated set of all the admissible equilibrium points is precisely defined.
