This volume contains the proceedings of ADHS’06: the 2nd IFAC Conference on Analysis and Design of Hybrid Systems, organized in Alghero (Italy) on June 7-9, 2006.


ADHS is a series of triennial meetings that aims to bring together researchers and practitioners with background in control and computer science in order to provide a survey of the advances in the field of hybrid systems and of their ability to take up the challenge of analysis, design and verification of efficient and reliable control systems. ADHS'06 is the second Conference of this series after ADHS'03 in Saint Malo. The ADHS series follows the successful conference series on the Automation De Processus Mixed / Automation of Mixed Processes (ADPM'92 in Paris, ADPM'94 in Brussels, ADPM'98 in Reims, ADPM'2000 in Dortmund). The continuity between the ADHS conferences is guaranteed by the IFAC Technical Committee on Discrete Event and Hybrid Systems (TC 1.3) that is the main technical sponsor of the series.


We express our gratitude to the authors of the papers submitted to ADHS'06. Out of 96 submissions, 65 papers were selected after a careful reviewing process during which each paper received, on the average, three reviews. The high quality of the program is due to the authors of the submitted papers, to the members of the International Program Committee and to the referees who provided accurate and extensive reports.


Among the 65 papers accepted and published in this volume, 52 are coming from Europe, 7.5 from US/Canada, 2.5 from Latin America, 2 from Japan, 0.5 from Egypt, 0.5 from Australia.


Three distinguished speakers have been invited to give a one hour plenary talk during the conference. They are: Vadim I. Utkin, whose talk is titled "Chattering Problem in Sliding Mode Control Systems"; Alberto Sangiovanni-Vincentelli, whose talk is titled "Challenges and Opportunities for System Theory in Embedded Controller Design"; Claude Iung, whose talk is titled  "Optimal Control in Hybrid Systems". The invited speakers have contributed to the proceedings with an extended abstract of their talk.


Some of the papers presented at the conference have been submitted as part of invited sessions. All of them went through the normal review procedure. We are grateful to the organizers of these sessions that have timely put into focus interesting new research topics. They are: E. De Santis organizer of a session on "Structural Analysis and Approximation of Hybrid Systems"; S. Engell and O. Stursberg organizers of a session on "Controller Design Based on Hybrid Models of Industrial Plants"; A. Bemporad and F. Lamnabhi-Lagarrigue organizers of a session on "Applications of Hybrid Control".


A special thank goes to C.G. Cassandras and P. Mosterman, organizers of an invited session on "Hybrid Simulation Tools: Principles, Challenges and Applications" that was also complemented by an interactive tool presentation. This session was composed by five presentations whose speakers have also contributed to the proceedings with an extended abstract of their talk.


We are grateful to the members of the Organizing Committee who took care of all important logistic and administrative details. In particular, we thank Maria Paola Cabasino for her help in preparing these proceedings. This conference benefits of support from the Università di Cagliari, from the Comune di Alghero and from Akhela s.r.l.
