This monograph is a little gem. It is a must read for everyone who deals with just as the problems of stability of dynamic systems and control design, so too mathematical modeling and simulation in all areas of modern natural philosophy and engineering. Why? First, because to a certain degree current science and technology are all about mathematical models. Second, after you have successfully constructed the adequate mathematical model of a physical process the next step you have to make is checking its stability out. This sine qua non is dictated by thousand years of human experience...
