A sampled-data system
is a control system
where a continuous-time plant (control theory)
is controlled with a digital device. Under periodic sampling, the sampled-data system is time-varying but also periodic, and thus it may be modeled by a simplified discrete-time system obtained by discretizing the plant. However, this discrete model does not capture the intersample behavior of the real system, which may be critical in a number of applications.
The analysis of sampled-data systems incorporating full time information leads to new challenging control problems with a rich mathematical structure. Many of these problems have been solved only very recently.

control systems are largly used in modern days. One of the good example is auto mobile companies.
