The topics of control engineering and signal processing continue to ?o- ish and develop. In common with general scienti?c investigation, new ideas, concepts and interpretations emerge quite spontaneously and these are then discussed,used,discardedorsubsumedinto theprevailingsubjectparadigm. Sometimes these innovative concepts coalesce into a new sub-discipline within the broad subject tapestry of control and signal processing. This p- liminary battle between old and new usually takes place at conferences, through the Internet and in the journals of the discipline. After a little more maturity has been acquired by the new concepts then archival publication as a scienti?c or engineering monograph may occur. A new concept in control and signal processing is known to have - rived when suf?cient material has evolved for the topic to be taught as a specialised tutorial workshop or as a course to undergraduate, graduate or industrial engineers. Advanced Textbooks in Control and Signal Processing are designed as a vehicle for the systematic presentation of course material for both popularand innovative topics in the discipline. It is hoped that prosp- tive authors will welcome the opportunity to publish a structured and s- tematic presentation of some of the newer emerging control and signal p- cessing technologies in the textbook series.
