Sampled-data-based dissipative control of T-S fuzzy systems
Applied Mathematical Modelling, 2019 This paper investigates the problem of sampled-data-based dissipative control of Takagi–Sugeno (T-S) fuzzy systems. The sampling period is assumed to be varying within an interval.

Invariance of sampled-data and adaptive sampled-data systems
IFAC Proceedings Volumes, 1963Summary In the report it is shown that the invariance conditions can be used successfully in usual continuous control systems and also in sampled- data control systems. This is especially important in adaptive impulse systems. In the first section of the report fundamentals of invariance theory of combined sampled-data systems are considered.

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.

2009 IEEE Custom Integrated Circuits Conference, 2009
The papers in this session highlight both emerging applications of over-sampling techniques and newer methods of their implementation in traditional analog-to-digital converters architectures. Performance enhancement techniques for both discrete- and continuous-time oversampled analog-to-digital converters are presented.

Sampling and sampled-data models
Proceedings of the 2010 American Control Conference, 2010Physical systems typically evolve continuously whereas modern controllers and signal processing devices invariably operate in discrete time. Hence sampling arises as a cornerstone problem in essentially all aspects of modern systems science. This paper reviews various aspects of sampling of signals and systems.

Techniques for Warehousing of Sample Data
22nd International Conference on Data Engineering (ICDE'06), 2006We consider the problem of maintaining a warehouse of sampled data that "shadows" a full-scale data warehouse, in order to support quick approximate analytics and metadata discovery. The full-scale warehouse comprises many "data sets," where a data set is a bag of values; the data sets can vary enormously in size. The values constituting a data set can

Sketching Sampled Data Streams
2009 IEEE 25th International Conference on Data Engineering, 2009Sampling is used as a universal method to reduce the running time of computations -- the computation is performed on a much smaller sample and then the result is scaled to compensate for the difference in size. Sketches are a popular approximation method for data streams and they proved to be useful for estimating frequency moments and aggregates over ...

The analysis of contact sampling data
Oecologia, 1980Use of the chi-square statistic for investigating interspecific association has been incorrectly applied to the contact sampling method because of an invalid probability argument. The usual method of calculating expected frequencies leads to a large overestimation and hence bias towards negative association.

Spectral analysis of irregularly-sampled data: Paralleling the regularly-sampled data approaches
Digital Signal Processing, 2006The spectral analysis of regularly-sampled (RS) data is a well-established topic, and many useful methods are available for performing it under different sets of conditions. The same cannot be said about the spectral analysis of irregularly-sampled (IS) data: despite a plethora of published works on this topic, the choice of a spectral analysis method ...

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 ...
