Part III: Time-Driven Versus Event-Driven Control

The inputs and outputs to and from a controller may be a function of time (or time-driven), which means that the control flow is driven by a clock; or things may be controlled by events (event-driven), which means that the control flow is determined by events, such as a sensor triggering or a user action or a message from another control system. Our expert will introduce the concepts of discrete (digital), continuous (analog), time-driven, and event-driven systems.
