What is meant by digital control system?
Digital control is a branch of control theory that uses digital computers to act as system controllers. Depending on the requirements, a digital control system can take the form of a microcontroller to an ASIC to a standard desktop computer.
What are the examples of digital control systems?
• 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 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 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.
