Unit 2: Introduction to Real-time Applications
we discuss a few example applications in some detail. As we can imagine, the list would become Notes
very vast if we try to exhaustively list all areas of applications of real-time systems. We have
therefore restricted our list to only a handful of areas, and out of these we have explained only
a few selected applications to conserve space.In this unit, we will discuss some applications of
real-time systems.
2.1 Digital Control
The introduction of digital computers in the control loop has allowed developing more flexible
control systems including higher-level functions and advanced algorithms. Furthermore, most
current complex control systems could not be implemented without the application of digital
hardware. However, the simple sequence sensing–control–actuation for the classical feedback
control becomes more complex as well. Nowadays, this sequence can be supplemented as follow:
sensing–data acquisition–control law calculation–actuation–data base update. Figure 2.1 shows
an overview of such control systems.
