(ii) the sizing and selection of the instrumentation involved in industrial process control as well as microelectromechanical devices and smart sensors; (iii) the use of microprocessors for process control, as well as signal conditioning and (iv) the sizing and the selection of actuating equipment for industrial processes. Numerous examples and case studies are used to illustrate formal modeling, hybrid controller design and the selection of instrumentation for electrical-driven machine actuation and DAQ related to systems dynamics and process operations. Through these case studies, the reader should gain practical understanding of topics related to the control system and instrumentation allowing him/her to fulfill a control and instrument engineering position where he/she is expected: (i) to possess a good knowledge of instrumentation operating conditions and control requirements; (ii) to size and select control instrumentation; (iii) to design, develop and implement digital controllers; (iv) to design engineering processes and electrical-driven systems; (v) to collaborate with design engineers and process engineers and technicians for the cost- and time-based acquisition of systems and processes control equipment and (vi) to perform technical audit to ensure instruments compliance with health and safety regulations.
This book is conceived to develop the reader's skills for engineering-based problem solving, engineering system design, critical analysis and implementation of control systems and instrumentation. It allows self-study via comprehensive and straightforward step-by-step modular procedures. In addition, examples with their accompanying MATLAB® routines, as well as design and selection related exercises and problems, are provided with their solutions. Furthermore, a dedicated textbook companion website allows the reader to download additional material for teaching, such as slide presentations of the chapter material, data files for additional laboratory sessions, example files as well as 2D and 3D innovative virtual labs of physical real-life systems (i.e. model-based simulation tools that could be associated to real life system for in-class lab sessions).
Suggestions for a teaching plan for applied control theory of mechatronic systems and electrical-driven processes would be as follows: (i) Chapter 1 through Chapter 5 (up to Section 5.3.1) for an introductory digital control level course during a semester; (ii) Chapters 2, 3 and 5 (Sections 5.3 and 5.4) for advanced control students with a control theory background; (iii) Chapters 1, 3 (Sections 3.3 and 3.4) and 8 for electric-driven machine and instrumentation students with computer hardware and software programming experience; (iv) Chapters 2, 3 (Sections 3.3 and 3.4), 5 (Sections 5.2.4, 5.3 and 5.4) and 6–8 for field control and instrumentation engineers interested in the design or the migration of process control of hybrid systems.

1 Introduction to the Control of Mechatronic Systems
1.1 Introduction
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.
1.2 Description of Mechatronic Systems
Mechatronic systems are either electrically-driven products or technical processes. Electrically-driven products are machines transforming current, voltage, or other electrical power into mechanical, fluidic,
