"The book can serve as an excellent basis for a graduate course on control and stabilization of multi-body mechanical systems. It provides a researcher with a comprehensive account of approaches and methods of designing controls stabilizing unstable equilibria. It will be a valuable reference to the classical and modern literature on the subject."Oleg N. Kirillov in: Mathematical Reviews Clippings, July 2018, MR3726859
