Nonlinear Sampled-Data Systems
, 2014 Sampled-data systems are control systems in which the feedback law is digitally implemented via a computer. They are prevalent nowadays due to the numerous advantages they offer compared to analog control. Nonlinear sampled-data systems arise in this context when either the plant model or the controller is nonlinear.

For digital devices to interact with the physical world, an interface is needed that transforms the signals from analog to digital and vice versa. Ideal samplers and zero-order hold devices are incorporated to derive discrete-time models of continuous-time systems. State variable descriptions and transfer functions are used.

Minimality of aperiodic sampled data systems
2017 American Control Conference (ACC), 2017This article studies the relation between the minimality properties of two different types of models encountered in the context of linear time-invariant (LTI) sampled-data systems with aperiodic sampling. More precisely, we consider the problem of determining the relationship between the minimality of a continuous-time LTI state-space (SS ...

Hankel norm of sampled-data systems
IEEE Transactions on Automatic Control, 1995Summary: We generalize the concept of Hankel norm for purely continuous-time systems to sampled-data systems. The Hankel norm of a sampled-data system is defined by taking into account the intersample behaviors. The formula of the Hankel norm of a sampled-data system is given by a hybrid state-space model approach. We show that the Hankel norm is equal

The notion of zeros of sampled-data systems is introduced in the lifting framework so that from the continuous-time viewpoint the zeros have signal transmission blocking properties. A characterization of all such zeros is given in terms of the eigenvalues of a bounded operator on the state space.
