Series Editors’ Foreword
The Advanced Textbooks in Control and Signal Processing series is designed as a vehicle for the systematic textbook presentation of both fundamental and innovative topics in the control and signal processing disciplines. It is hoped that prospective authors will welcome the opportunity to publish a more rounded and structured presentation of some of the newer emerging control and signal processing technologies in this textbook series. However, it is useful to note that there will always be a place in the series for contemporary presentations of foundational material in these important engineering areas.
The Editors of the series Advanced Textbooks in Control and Signal Processing, whilst seeking new and advanced topics where a“critical mass”of material indicates a consolidation worthy of textbook presentation, are also striving to create a balanced series. Advanced textbooks come in a variety of guises. These include pure theory textbooks and theory textbooks with illustrative academic examples. A little rarer are the theory textbooks with practical applications as might be found in a textbook with laboratory-based experiments or some industrial applications of the theory. Then the emphasis of a textbook can be switched round so that it is predominately applications orientated and the objective is to present the use of theory in the sole context of an industrial or applications ﬁeld. It can be quite difﬁcult for Series Editors to achieve these balanced aims for a series. Looking at the Advanced Textbooks in Control and Signal Processing series, there is a good representation from the category “advanced theory with academic examples”. However, for this textbook Automatic Control: Techniques, Design and Applications, we can take a slightly different viewpoint, namely, that in university engineering education,a really good grasp of the fundamentals must be imparted to students as the foundations on which to build the advanced studies.
For the subject of control engineering, it seems essential that all electrical, electronic, mechanical and chemical engineers have a “fundamentals” course on control and appreciate the importance of feedback in applications. As a consequence, the Series Editors have been seeking the elusive textbook that has a very strong component of control “fundamentals” to add to the series list. The ideal course textbook would subsume the wealth of classical control knowledge into a seamless whole with state-space and nonlinear systems, a text that would continually reinforce that the mathematical model of a process is simply that a “model”representation and not the system per se. If the author can make recourse to their own experience with a range of real-world applications to illustrate the theory in a non-trivial way, then the “fundamentals” course textbook will be valued by graduates in the years after within their own professional practice as an engineer.
Professor Stephen Dodds (University of East London,UK)has had an interesting career in control engineering with in-depth experience of and international research in three control applications areas: satellite attitude control (with the European Space Agency whilst employed with Marconi Space Systems), AC electrical drives and loudspeaker active control. Added to this direct practical experience and research leading to innovative control techniques are the many years of lecturing and the teaching of control that Professor Dodds gave at undergraduate and masters level.
Professor Dodds has distilled this practical work with real-world applications and used his academic lecturing and teaching experience to produce this comprehensive course textbook that is noteworthy for its distinctive presentation of the “fundamentals” of control engineering. The text gives a careful explanation of concepts and always points up the practical relevance of the ideas under discussion. Where mathematical proof or justiﬁcation is needed, much care is devoted to the clarity of the exposition. The exhaustive coverage given in the textbook will also ensure that the student has a control textbook that will serve as a substantial reference book for future years, whether following a career in applications or in a research ﬁeld.
Finally, Professor Dodds makes recourse to his industrial and commercial work to provide illustrative examples that seriously reﬂect the control applications of the real world. Downloadable web-based materials are available to supplement the material of this course textbook.
In conclusion the Editors of the Advanced Textbooks in Control and Signal Processing series are pleased to welcome Professor Dodds’ textbook into the series, contributing as it does to the Editors’ aim of having a good control fundamentals” textbook in the series.

I have owned a Falco e-bike motor for a couple of years and have been very impressed with it. The idea of using the e-bike as an indoor exercise bike which also re-charges the battery is brilliant!James
I have been investigating e bikes for some considerable time. As a cyclist in past years such concepts have much potential and the Falco is every bit revolutionary in as much it generates its own driving ability unlike most systems one can only recharge via electric power. I would give it a 10 out of 10 for everything it has proven.Richard
The whole concept is impressive, as well as all of the tech & usability you get from such a compact hub. Being able to retro fit the bike you love & bring it into the ebike world is fantastic & they make it a very user friendly process to accomplish. After meeting with the CEO directly at CES 2017 I have nothing but great hopes for Falco & their future.S. Morris
ECITI REVIEW AT CES
I had a chance to ride eCiti at CES. It is quite impressive that you have both top of the line eBike technology and smart power trainer technology all combined into one. I have ordered mine and I can not wait to get it. I wish you guys tremendous luck. I am a great fan of your product and innovation.Allen Clark
