In this chapter, the main features of the newly proposed control design methodology are presented. First, the class of systems to be considered is defined, and the key points in the design approach are drafted. Then, an introductory example allows the understanding of the main properties and to state the procedure to design the control. The Linear Algebra-Based Control Design (LAB CD) methodology is then outlined and the properties of the controlled plant are analyzed. Its applicability in DT is shown to be immediate, and the treatment of uncertainties and disturbances is introduced. Finally, a summary of the LAB CD approach, as a guideline for its application to a variety of processes in the following chapters, is given.
