Chapter 2, “Continuous-Time Models”

We shift our focus from continuous-time models and controllers to discrete-time models and controllers. Application of computer control systems necessitates this representation. The computer is a discrete-time device that can only measure (i.e., collect data from sensors) and take control action at discrete points in time. A typical DCS (distributed computer control system) employed in the process ...
