Model validation is a means of assessing the applicability of a given model with respect to experimental data. We consider a sampled‐data approach, using a continuous time model, including unknown perturbations and signals, and a discrete experimental datum of finite length. The sampled‐data model validation problem can be formulated as a linear matrix inequality problem.

Instead we examine if sampled-data nmpc based on a nominal model possess certain inherent robustness properties with respect to small model uncertainties and disturbances. We note that the results derived show similarities to the discrete time results presented in [39].
In this paper, we study delay-dependent lq control for sampled-data linear sys-tems. First, our delay model is more general than that in the above previous studies. Indeed, in the model we con-sider, the present delay is determined by the last few delays like in an autoregressive.
For linear systems, exact sampled-data models can be obtained. These models, however, will generally have more zeros than the continuous-time model. In this paper we show that there is a specific relation between the characterization of these sampling zeros and the order of the b-splines used to generate the continuous-time input to the system.

This paper considers properties of zeros of sampled-data models for linear time delay systems. Two types of holds; a zero-order hold and a fractional-order hold are treated as a hold. The first order approximate expressions for the zeros with respect to a small sampling period are derived by focusing attention on a normal form of the continuous-time systems.
In this paper, the problem of sampled‐data model predictive control (mpc) is investigated for linear networked control systems with both input delay and input saturation. The delay‐induced nonlinearity is overapproximatively modeled as a polytopic inclusion. The nonlinear behavior of input saturation is expressed as a convex polytope.
This way, we may receive samples that lie outside the space of our real data generation process. Because almost all machine learning models are well defined.
This chapter shows how approximate sampled-data models for stochastic-linear systems can be developed. In the linear case exact sampled-data models can always be obtained. However, results on approximate linear-stochastic sampled-data models are developed here, as a prelude to the nonlinear case treated in the next chapter.

A new approach for identifying continuous time models from discrete time sampled-data records is presented. The proposed method involves estimating and validating a discrete time model, linear or non-linear, based on sampled data records, evaluating the discrete time linear and non-linear frequency response functions and then curve fitting to the frequency response data to yield a continuous.
The sma models and ses models assume that there is no trend of any kind in the data (which is usually ok or at least not-too-bad for 1-step-ahead forecasts when the data is relatively noisy), and they can be modified to incorporate a constant linear trend as shown above.

Linear mixed models are an extension of simple linear models to allow both fixed and random effects, and are particularly used when there is non independence in the data, such as arises from a hierarchical structure. For example, students could be sampled from within classrooms, or patients from within doctors.
This paper is concerned with the sampling-interval-dependent stability of linear sampled-data systems with non-uniform sampling. A new lyapunov-like functional is constructed to derive sampling-interval-dependent stability results.
Sampled models for linear systems with deterministic inputs are first considered, for which exact sampled-data model can be obtained. Unless stated explicitly otherwise, it is assumed that the anti-aliasing filter, if present, is included as part of the continuous-time system model.

The authors use a parameterisation of the sampled-data model in incremental form in order to modify the standard formulation of the em algorithm for discrete-time models. The parameters of the incremental model converge to the parameter of the continuous-time system description as the sampling period goes to zero.
Sampled-data models for linear and nonlinear systems provides a fresh new look at a subject with which many researchers may think themselves familiar. Rather than emphasising the differences between sampled-data and continuous-time systems, the authors proceed from the premise that, with modern sampling rates being as high as they are, it is becoming more appropriate to emphasise connections.

In this paper a non-linear sampled data model for fourth order dc-dc converters is developed. This model closely depicts the effect of large-signal variation in duty ratio caused due to large-signal disturbances such as load/source transients, which linear small-signal models and other non-linear models generally fails to predict. Large-signal linearization is applied to the exact discrete.
