Stability theory for linear time-invariant plants with periodic digital controllers. (English) Zbl 0651.93053

The authors consider the control of a linear time-invariant plant by a digital controller composed of a sampler, a periodic discrete-time component, and a zero-order hold. It is shown how closed-loop zeros can be placed using such a scheme. The design procedure is constructive, using state-space methods.
