Nonlinear Stabilization Under Sampled and Delayed Measurements, and With Inputs Subject to Delay and Zero-Order Hold

I. Karafyllis, M. Krstic
2012 IEEE Transactions on Automatic Control  
All the results employ "nominal" feedback laws designed for the continuous-time systems in the absence of delays, combined with "predictor-based" compensation of delays and the effect of sampling.  ...  Sampling arises simultaneously with input and output delays in networked control systems.  ...  Our delay compensation methodology guarantees that any controller (continuous or sampled-data) designed for the delay-free case can be used for the regulation of the delayed system with input/measurement  ...

Sampled-data iterative learning control for a class of nonlinear networked control systems

Ya-Jun Pan, H.J. Marquez, Tongwen Chen
2006 2006 American Control Conference  
In this paper, a sampled-data iterative learning control (ILC) approach is proposed for a class of nonlinear networked control systems.  ...  In the networked control systems (NCS), because of the existence of time delays and packet losses in input and output signal transmissions, remote stabilization of linear systems is not an easy task.  ...  For a linear system with input time delay only, in [8] , the authors proposed a sampled data iterative learning control to ensure the stability of the closed loop system which can be unstable if the control  ...

2020 arXiv   pre-print
control design in linear discrete-time time-delay systems with uncertain delays.  ...  Since in many engineering applications time delays naturally arise and are often a source of instability, we contribute to the data-driven control field by introducing data-based formulas for state feedback  ...  In Section 3, a data-based representation for linear discrete-time time-delay systems is introduced.
