What is digital control system?
Digital control systems are usually have a mixture of continuous-time and discrete-time behavior. The control object exists continuously in time (thus the differential equation representation) while the controller is active only for brief periods of time.
What are the components of digital control system?
Usually, a digital control system consists of an A/D conversion for converting analog input to digital format for the machine, D/A conversion for converting digital output to a form that can be the input for a plant, and a digital controller in the form of a computer, microcontroller or a programmable logic controller.
What is an example of a digital control system?
• Examples 1
a) Residential heating and air-conditioning systems controlled by a thermostat ( temperature sensor). b) The cruise (speed) control of an automobile. c) Automatic hot water heater. d) Control system which automatically turns on a room lamp at dusk, and turns it off in daylight.
What are the 5 basic elements of a control system?
A feedback control system consists of five basic components: (1) input, (2) process being controlled, (3) output, (4) sensing elements, and (5) controller and actuating devices.
