What Does Digital Control Mean?
Digital control is a branch of control theory that makes use of digital computers for acting as controllers for a system. Here, a computer is responsible for the implementation of the control algorithm. A digital control system is also capable of taking the form of a microcontroller to an application-specific integrated circuit and even to a desktop computer, largely depending on the need. 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.
