Preface
Maglev (derived from magnetic levitation) is a system of transportation that sus-
pends,guidesandpropelsvehicles,predominantlytrains,usingmagneticlevitation
from a very large number of magnets for lift and propulsion. In terms of the
magnetismbetweenmagnetsandmagneticcomponentsonthetrack,Maglevtrain
is attractedto suspendabovethe track.The traveloftrain dependson the traction
of linear motors in the vehicle. In order to ensure the safe operation of Maglev
train, some key technologies must be adopted and realized, such as suspension
and orientation technology,safe braking technology,position and speed detection
technology, control and diagnosis technology. In the book, we present them and
provide corresponding new technologies or ideas on control and diagnosis of
Maglev train. We hope the contentsof the book can providesome referencesand
helps for the researcher, scholar, engineer on Rail Transit industry and Maglev
technology.
Thebookcomprisessixchapters,coveringabout200pages.Thesechapterswere
writtenbyZhigangLiu,ZhiqiangLongandXiaolongLifromSouthwestJiaotong
UniversityandNationalUniversityofDefenseTechnologyinChina.
The book begins with an introduction of Maglev train. In Chap. 1, the char-
acteristics and classification of Maglev train are presented. Some research and
major achievementsof Maglev train key technologiesare discussed in detail. The
technologycharacteristicsofhigh-speedMaglevtrainandlow-speedMaglevtrain
are presented. Specially, the technology characteristics of TR08 Maglev train are
discussed,andtheoveralldesignideaofTRMaglevtrainisoutlined.InChap.2,the
technologydevelopmentandapplicationresearchofMaglevcontrolarediscussed
andsummarized,mainlyincludingsuspensioncontrolplanandsuspensioncontrol
algorithmsofMaglevtrain.Chapter3discussesthemodelingandcontrollerdesign
of suspension system of Maglev train in detail. They mainly include building
single point suspension model, design of control system, optimization of control
parameters under the condition of output saturation, design of signal filter of
suspension control system and experimental research. Chapter 4 discusses the
control and diagnosis system of Maglev train, which mainly includes on-board
control and diagnosis system, comprehensive assessment algorithm of on-board

faults based on fuzzy comprehensive assessment, and comprehensive assessment
method based on EDA (estimation of distribution algorithm). In Chap. 5, the on-
boardcontrolanddiagnosisnetworksofMaglevtrainareintroduced.Maincontents
include the communication simulation of on-board diagnosis network, integrated
networkdesignofthecontrolanddiagnosisnetworks,diagnosisnetworkbasedon
ADS,controlanddiagnosisnetworksbasedonroleautomationdecentralization,and
on-boardcommunicationplatforminMaglevtrainbasedonRTLinux.InChap.6,
the position and speed detection technology based on loop-cable for low-speed
Maglevtrainis introducedanddiscussed indetail. Maincontentsincludeposition
andspeeddetectionbasedontheXORpulse,positionandspeeddetectionbasedon
sampling,andexperimentsandsystemimplementation.
One important feature of the book is that some new technologies or ideas on
controlanddiagnosisofMaglevtrainareproposedanddiscussed.Theexperiments
