Explain the concept of discrete process control and provide examples of parameters and variables that are typically discrete in nature.
Explain the concept of discrete process control and provide examples of parameters and variables that are typically discrete in nature.
Discrete process control refers to control systems that operate on parameters and variables that change at discrete moments in time. Examples of discrete parameters and variables include binary values such as 0 or 1, off or on, open or closed. Examples of sensors and actuators for discrete control include limit switches, photo-detectors, timers, motors, valves, and clutches.
