Cadenced runs of impulse and hybrid control systems

Impulse differential inclusions, and in particular, hybrid control systems, are defined by a differential inclusion (or a control system) and a reset map. A run of an impulse differential inclusion is defined by a sequence of cadences, of reinitialized states and of motives describing the evolution along a given cadence between two distinct consecutive impulse times, the v alue of a motive at the end of a cadence being reset as the next reinitiali zed state of the next cadence. A cadenced run is then defined by constant cadence, initial state and motiv e, where the value at the end of the cadence is reset at the same reinitial ized state. It plays the role of a 'discontinuous' periodic solution of a d ifferential inclusion. We prove that if the sequence of reinitialized states of a run converges to some state, then the run converges to a cadenced run starting from this st ate, and that, under convexity assumptions, that a cadenced run does exist.
