From the book reviews: In this book, some mathematical models arising in fermentation processes are presented. They are in the form of a nonlinear multistage system, switched autonomous system, time-dependent switched system, state-dependent switched system, multistage time-delay system, or switched time-delay system. ... The book is addressed to graduate and postgraduate students as well as to control engineers and researches. (Bozhidar Cheshankov, zbMATH, Vol. 1305, 2015)
