Preface
This edited book covers recent developments on fractional dynamics, time-delaysystems, system synchromzatIOn, and neuron dynamIcs.
FractIOnal calculus IS extensIvely used as a powefful tool to mvestigate complexphenomena in engmeenng and SCIence, and has receIved renewed attention recently.Chapter I of the book investigates fractional dynamics of complex systems. Somerecent results and applications in fractional dynamics are presented. In Chapter 2,the synthesIs and applicatIOn of tractIOnal-order controllers are presented. ThIs ISan active area of research. The tractIOnal-order PID controllers are desIgned for thevelOCity control of an expenmental modular servo system. The system consists ofa digital servomechanism and open-architecture software environment for real-timeimplementation. Experimental results of fractional-order controllers are presentedand analyzed. The effectiveness and superior perfonnance of the fractional-ordercontrols are compared WIth c1asslcalmteger-order PID controllers.
TIme delay IS a common phenomenon in engmeenng, economIcal and bIOlogIcalsystems, and has become a popular research topic in recent years. InChapter 3, equilibrium stability, Lindsedt's method and Hopf bifurcation, and transient behaviorsin differential-delay equations are presented. Multiple-scale and the center manifold analysIs are addressed. These methods are applied to mvestigate dynamIcalbehavIOrs of a differential-delay system modeling a sectIOn of the DNA molecule.Chapter 4 focuses on the methodologIes for time-domam solutIOns and control design of time-delayed systems. Method of semi-discretization and continuous timeapproximation are discussed. The spectral properties of the methods will be investigated. A comparative study of stabIlity of time-delayed linear time mvanant systemsIS carned out by the Lyapunov method, Pad approxImatIOn and semI-dIscretizatIOn.The methods of solutIOn for stochastic dynamIcal systems WIth time delay are alsodiscussed, and a number of control examples and an experimental validation arepresented.
Chapter 5 develops a theory for synchromzatIOn of multiple dynamIcal systemsunder constraints The metric functionals based on the constraints are introducedto descnbe the synchromCity of two or more dynamIcal systems. The chapter pro-
vi
vides a theoretic framework for designing controllers of slave systems which can besynchronized with master systems.
Finally in Chapter 6, complex dynamics of neurons with time-delay, stochastICIty and ImpulsIve dIscontmUIty are presented. Complex dynamIcal behavIOrs mclude perIOdIC spIkmg, chaotIc spIkmg, perIOdIC and chaotIc burstmg, and synchronization. In this chapter, a comprehensive review on recent developments and newresults in nonlinear neural dynamics are presented.
It is our hope that the book presents a reasonably broad view of the state-ofthe-art of complex systems, and provIdes a useful reference volume to SCIentIsts,engmeers and students. Furthermore, we hope that the book wIll stImulate moreresearches m the rapIdly evolvmg and mterestmg field of complex systems.
