Title: About observers of hybrid systems
Abstract: I recently reviewed the very nice paper [1] by Pauline Bernard and Ricardo Sanfelice about an observer design for hybrid systems, whose ideas I would like to share with you. I will briefly recall the hybrid systems framework proposed by Goebel, Sanfelice and Teel [2]. Afterwards I will highlight the difficulties in designing an observer for these kind of systems, in particular, when the jump times cannot be observed directly. Then I explain the actual observer design proposed in [1].
