It is proved that during the sliding phase, if basic assumptions are made, the continuous control variable never saturates, while, during the reaching phase, the presence of saturating actuators can make the steering of the sliding variable to zero in finite time not always guaranteed. In the present paper, the original algorithm is modified in order to solve this problem: a new strategy is proposed, which proves to be able to steer the sliding variable to zero in a finite time in spite of the presence of saturating actuators. date: 2008-06 date_type: published publisher: IEEE pagerange: 4715 -4720 event_title: American Control Conference, 2008 id_number: 10.1109/ACC.2008.4587239 refereed: TRUE isbn: 978-1-4244-2078-0 book_title: Proceedings of the American Control Conference, 2008 official_url: http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=4587239&isnumber=4586444 citation: Ferrara, Antonella and Rubagotti, Matteo A sub-optimal second order sliding mode controller for systems with saturating actuators.
