This chapter discusses design considerations for industrial systems and processes when embedded systems allow to intelligently influence the system in real-time. It is shown that in such embedded systems the capability to adapt themselves to changing environments and/or to different operating conditions has to be exploited. If properly done, almost all performance indicators like accuracy, speed, robustness, insensitivity for disturbances, will improve. The challenge is to first study the process for which the behaviour has to be improved. Based on the characteristics of the process and its disturbances, one wishes to select among the hundreds of tools to achieve its goals. For the professional printer, this design process and its many compromises and choices will be illustrated. Consequently, the professional printer will be analysed for its specific characteristics whose behaviour can be influenced during printing. Based on these characteristics, appropriate control approaches are discussed in more detail to show how control can cope with uncertainty or changing parameters. With extensive and illustrative examples the various methods are compared and it is shown why some control approaches are preferred solutions in the large number of problems that are faced by professional printers.
