Consensusability of discrete-time multi-agent systems

i ACKNOWLEDGEMENT I would like to express my never ending gratitude to my advisor and committee chair, Professor Guoxiang Gu for his guidance, and constant motivation towards the completion of this thesis. His technical advice and suggestions helped me to overcome hurdles and kept me enthusiastic and made this work a wonderful learning experience. In addition, I would like to thank my committee members Professor Kemin Zhou and Professor Lu Peng for taking time out of their busy schedule and agreeing to be a part of my committee and for their valuable feedback. I also take this opportunity to thank Professor James J. Spivey for his moral and financial support throughout my studies at LSU. I would like to thank the faculty members of the Department of Electrical and Computer Engineering, whose classes I had the privilege of attending while completing my studies and making my study at Louisiana State University a pleasant experience. Finally, I would like to thank my family and friends without whom I would not have made it to this point.
