The book begins with the definition of time together with a brief description of its crucial properties and with the principles of the physical uniqueness and continuity of physical variables, which are essential for the natural tracking control synthesis. The book presents further new results on matrices, on polynomial matrices, on matrix polynomials and on the new compact, simple and elegant calculus that enabled the generalization of the transfer function matrix concept and of the state concept, the proofs of the new observability, controllability, trackability and tracking conditions, as well as the natural tracking control synthesis for all five classes of the treated linear systems.

Mr. Lyubomir T. Gruyitch is Certified Mechanical Engineer (Dipl. M. Eng.), Master of Electrical Engineering Sciences (M. E. E. Sc.), and Doctor of Engineering Sciences (D. Sc.) (All with the University of Belgrade, Serbia). Dr. Gruyitch was a leading contributor to the creation of the research Laboratory of Automatic Control, Mechatronics, Manufacturing Engineering and Systems Engineering of the National School of Engineers (Belfort, France), and a founder of the educational and research Laboratory of Automatic Control of the FME. He has published 13 books (in: English 12, Serb 1), 4 textbooks (in: Serb), 11 lecture notes (in: English 2, French 7, Serb 2), one manual of solved problems (in: Serb), one book translation from Russian, chapters in eight scientific books, 130 scientific papers in scientific journals, 173 conference research papers and two educational papers. Professor Gruyitch supervised one doctorate at the University of Technology Belfort-Montbeliard - UTBM (France), which gained the highest grade by an international (French - USA) jury, five doctorates at the University of Belgrade (Serbia), four DEA (equivalent to M. Sc.) theses at the ENI and five master theses at the University of Belgrade. Professor Gruyitch was a co-initiator of the proposal for a new tentative, highly advanced, Department of Automatique et Systémique at the UTBM, and the Coordinator of the team that worked out the full project. He was cofounder of the Cathedra of Automatic Control and of the undergraduate and graduate Group of Automatic Control of the FME. He introduced a number of new courses at the universities in France, South Africa and Serbia. He was the principal investigator supervising several projects funded by industry in Serbia. Professor Gruyitch was a member of the Acting Senate of the UTBM and the Coordinator of the Commission of Research of the UTBM. He was the Chief of the Cathedra of Automatic Control, the Chief of the Laboratory of Automatic Control and the President of the Senate of the Faculty of Mechanical Engineering, Belgrade. Dr. Gruyitch gave invited university seminars in Belgium, Canada, England, France, Russia, Serbia, Tunis and USA. He was invited plenary sessions speaker, Organizer and/or Chairman of invited sessions at the international conferences, and President of the International Program Committee of the IFAC - IFIP - IMACS Conference Control of Industrial Systems, Belfort, France (more than 300 participants from 42 countries with four continents).
