A calculus for hybrid sampled data systems
1994This paper addresses the problem of formally describing hybrid sampled data systems. Using the techniques proposed in Duration Calculus, we first develop a formal calculus, called Accumulation Calculus, for specifying real valued step functions of time. The key idea is that such functions are described using their integrals in bounded closed intervals.

Control of asynchronous sampled data systems
IEEE Transactions on Automatic Control, 1994This paper is concerned with the problem of controller design in the case of asynchronous sampled data systems. Optimal LQG controllers are obtained for the class of two-rate systems where all the control inputs are held at a rate which is asynchronously related to the rate with which all of the outputs are sampled.

Some Remarks on the Controllability of Sampled-Data Systems
SIAM Journal on Control and Optimization, 2012This paper raises the question of controllability (or more precisely, reachability) of sampled-data systems, i.e., systems composed of a continuous-time plant controlled by a digital controller. The question is formulated from the continuous-time perspective, and the study is carried out in a functional analytic framework. The novelty of the study lies

Analysis of Sampled-Data Systems
2018In sampled-data systems the signals are handled and stored in digital form. In these systems continuous time signals are sampled periodically at sampling instants and their processing takes place in the discrete time domain. In computer control systems the output of the continuous process is sampled and this signal is forwarded to the process control ...

Status of sampled-data systems
Transactions of the American Institute of Electrical Engineers, Part I: Communication and Electronics, 1960This paper briefly describes in general terms procedures for analysis and methods of synthesis of sampled-data systems and indicates present areas of research and some of the important problems to be tackled in this field.

Sensitivity in sampled-data systems
IEEE Transactions on Automatic Control, 1963The sensitivity of sampled-data systems to plant variations and load disturbance is examined with reference to two fundamental configurations. It is shown that the sensitivity function of a sampled-data system containing no continuous feedback is theoretically limited if the plant possesses low-pass response characteristics.
