Sampled data system

In <a href="/facts/Systems_science/necfqoog">systems science</a>, a sampled-data system is a <a href="/facts/Control_system/8CEjIDlS">control system</a> in which a continuous-time <a href="/facts/Plant_(control_theory)/6lK80ETg">plant</a> is controlled with a digital device. Under periodic <a href="/facts/Sampling_(signal_processing)/xxck7aLN">sampling</a>, the sampled-data system is time-varying but also periodic; thus, it may be modeled by a simplified discrete-time system obtained by discretizing the plant. However, this discrete model does not capture the inter-sample 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 challenging control problems with a rich mathematical structure. Many of these problems have only been solved recently.
