This book - the first of its kind - introduces the reader to the inherent characteristics of nonlinear DAE systems and the methods used to address their control, then addresses the significance of DAE systems into the modeling and control of chemical processes. Control of Nonlinear Differential Algebraic Equation Systems presents in a unified framework recent results on the stabilization, output tracking, and disturbance elimination for a large class of nonlinear DAE systems. This book should be of interest to applied mathematicians, control engineers, and chemical engineers.
