Journal ArticleDOI
New predictive scheme for the control of LTI systems with input delay and unknown disturbances
TL;DR: It is proved that the new scheme leads to feedback controllers that are able to reject perfectly constant disturbances and for time-varying ones, a better attenuation is achieved for a wide range of perturbations and for both linear and nonlinear controllers.
Journal ArticleDOI
Delay Estimation and Predictive Control of Uncertain Systems With Input Delay: Application to a DC Motor
Vincent Léchappé,Sebastien Rouquet,Alberto Gonzalez,Franck Plestan,Jesus de Leon,Emmanuel Moulay,Alain Glumineau +6 more
TL;DR: A recent predictive control method developed to attenuate the effect of external disturbances is shown to be also robust to parameter uncertainties, and a delay estimator is presented to estimate unknown time-varying delays.
Journal ArticleDOI
Discrete predictor-based event-triggered control of networked control systems
TL;DR: A predictor-based controller combined with two event-triggering mechanisms is proposed in order to control an LTI system over a network to limit the number of packets sent over the network while preserving the ultimate boundedness of the solutions.
Journal ArticleDOI
Robust fixed-time stability: application to sliding mode control
TL;DR: In this article, robust fixed-time stability and stabilization of a class of uncertain nonlinear second-order systems is studied. But the authors focus on scalar systems and do not consider the second order systems with constant and variable exponent coefficients.
Journal ArticleDOI
Delay and state observation for SISO nonlinear systems with input delay
TL;DR: The main idea is to approximate the delayed input by using Taylor's theorem and to create an extended system with the delay as part of the extended state, using the construction of an observer to estimate both state and delay.
