Partial Stability and Control

Unlike the conventional research for the general theory of stability, this mono­ graph deals with problems on stability and stabilization of dynamic systems with respect not to all but just to a given part of the variables characterizing these systems. Such problems are often referred to as the problems of partial stability (stabilization). They naturally arise in applications either from the requirement of proper performance of a system or in assessing system capa­ bility. In addition, a lot of actual (or desired) phenomena can be formulated in terms of these problems and be analyzed with these problems taken as the basis. The following multiaspect phenomena and problems can be indicated: • "Lotka-Volterra ecological principle of extinction;" • focusing and acceleration of particles in electromagnetic fields; • "drift" of the gyroscope axis; • stabilization of a spacecraft by specially arranged relative motion of rotors connected to it. Also very effective is the approach to the problem of stability (stabilization) with respect to all the variables based on preliminary analysis of partial sta­ bility (stabilization). A. M. Lyapunov, the founder of the modern theory of stability, was the first to formulate the problem of partial stability. Later, works by V. V. Rumyan­ tsev drew the attention of many mathematicians and mechanicians around the world to this problem, which resulted in its being intensively worked out. The method of Lyapunov functions became the key investigative method which turned out to be very effective in analyzing both theoretic and applied problems.

"Lucid and very well written.... Very suitable for graduate students of mathematics and engineering, in optimal control theory, as well as research professionals in the area. The book has many worked examples taken entirely from aerospace applications. It would thus also appeal to design engineers who work in aerospace or complex-manufacturing operations provided they have the willingness to accept rigorous mathematical arguments or maturity in functional analysis and differential equations. With nearly 400 references, this book provides a rich resource for further study and should be in the library of every graduate college mathematics and engineering department and every industrial R&D laboratory with interests in the control area." —Applied Mechanics Reviews

 

"This book deals with problems on stability and stabilization of dynamical systems with respect to a given part of the variables characterizing these systems. The theory goes back to Lyapunov, who was the first to formulate these kinds of problems. Here the author develops a new method based on transformation of original systems in some more convenient systems.... A number of problems of controlling the angular motion of an asymmetric solid in various formulations as well as problems of stabilizing an artificial satellite in circular and geostationary orbits are solved, as an illustration of the efficiency of the method proposed. The monograph is based mainly on the author’s results published in the last two decades. It is a valuable reference for advanced graduates and specialists in applied mathematics and engineering engaged in research involving differential equations, differential games, stability and control." —Applications of Mathematics

 

"This monograph gives a detailed and comprehensive study of the stability and stabilisation of dynamical systems with respect to part of thevariables.... The monograph begins with an excellent Introduction. This places the topic of the monograph clearly in the historical development of the partial stability of dynamical systems, [and] includes a detailed account of the relevant literature and makes use of the monograph's comprehensive bibliography. Several situations are then described which help motivate and justify the need for a study of partial stability/stabilisation.

This is a well-written book. At well over 400 pages there is much to discover and digest. There are numerous useful examples, both of a textbook style, aimed to clarify a definition or detail in a proof, and those of a more significant application-based style. I found the applications to the control of geo-stationary orbit of satellites most interesting and illuminating. Each chapter is clearly introduced and each concludes with an extensive and impressive overview of the literature." —UK Nonlinear News
