Digital control system applications
Digital Control System is a branch of the control system with continuous time processes in the region associated with the digital controller as the controller of the control elements that control systems and computing discrete time. Depending on requirements, a digital controller can be shaped microcontroller and ASIC to a standard desktop computer. Because the digital computer system is discrete, then the Laplace transform is used in the control system is replaced with the Z-transform. Therefore, you must understand about the concept of continuous time and discrete time concept.

Digital computer also has a limited precision (See quantization) extra care needed to ensure that errors in the coefficients, A / D conversion, D / A conversion, etc. do not produce unwanted effects or planned.
The application of digital control can easily be done when used in a feedback form. Since the creation of the first digital computer in the early 1940s the price of digital computers has dropped significantly. The reason this is one of the many reasons for the application of digital control systems for the control of the control system. Other reasons:
Flexibile: easy to configure and reconfigure through software
* Scalable: can be set up programs tailored to the limits of memory or storage space at no extra cost
* Adaptable: program parameters can be changed with the times
* Static operation: digital computers are much more susceptible to environmental conditions rather than of capacitors and inductors
