The rapid expansion of automated electrically-driven systems (e.g. electromechanical machines) is related to the development of digital control strategies in order to enhance their performance and extend their functionality while significantly reducing their operating cost and complexity. However, those digital control strategies are dependent on the performance of the control instrumentation related to measurement, signal conditioning, actuating, and digital control technologies. Recent technology advancements offer a plethora of control systems instrumentation, each with design-specific requirements and compliance constraints. Hence, in addition to system modeling, the design of digital control strategies has to consider: (i) the selection of control instrumentation in accordance with performance objectives; and (ii) the integration of the control systems instrumentation and process equipment with respect to operating constraints.

Consequently, it is suitable to lay out a generic design procedure for digital control systems, especially in: (i) controlling electrically-driven systems; (ii) sizing and selecting control instrumentation related to information processing and computing, electrically-driven actuation, process sensing and data acquisition; (iii) integrating those control instrumentation with respect to controlled system performance objectives and operating constraints; and (iv) integrating multifunctional control applications.

In this chapter, the definition and classification of electrically-driven systems and technical processes are presented first. Then the functional relationship between electromechanical machine control and control within interconnected and synchronized electromechanical systems is outlined. Various components of control systems instrumentation are described along with their design requirements. Furthermore, major steps of control system migration projects are presented with some illustrative examples of industrial process control. Finally, key project management steps and the associated subsequent design documents are listed.
