INTRODUCTION

Automatic control systems permeate life in all advanced societies today. This development has evolved more complex systems in which nonlinearities need to be more effectively addressed in the design process. Such systems act as catalysts in promoting progress and development propelling society into the 21st century. Technological developments have made it possible for high-speed bullet trains; exotic vehicles capable of exploration of other planets and outer space; safe, comfortable and efficient automobiles; sophisticated civilian and military aircrafts; efficient robotic assembly lines; advanced renew energy plants; and efficient environmentally friendly pollution controls for factories. The successful operation of all of these systems depends on the proper functioning of the large number of control systems used in such ventures.
