“…However, it is extended to the time-varying delay case. In addition, the exponential stability (only asymptotic stability was proved in [18]) is proved for a larger class of observers and controllers. The technique is to design various cascaded observers-predictors; Each observer-predictor will predict the state for a fraction of the delay denotedh.…”

“…The idea has also been used for the observation of systems with delayed output [15], [16], [17]. Recently, some works have used the same idea of dynamic prediction for control purposes: [18] with full state knowledge, [19] and [20] considering sample and hold phenomena.…”

Abstract-A predictive-based controller is proposed to control LTI systems in presence of time-varying delay in the input. The control method is based on the computation of an approximated (or asymptotic) prediction thanks to a dynamic system. Then, this prediction is "plugged" into any Lipschitz controller that stabilizes the delay-free system. Explicit conditions that guarantee the closed-loop stability are given thanks to a Lyapunov-Krasovskii analysis. A qualitative analysis of these conditions is performed and the results are illustrated in simulation.

“…If gain matrix L p is designed so that the error dynamics (Equation ) is asymptotically stable, then the state of the predictor system X p ( t ) can be assumed as a estimation of the future values of X ( t ) . There are some theorems to address the stability of error dynamics (Equation ) that are borrowed from Najafi et alTheorem There always exists a maximum delay value d * such that for d ∈ [0, d * ], error dynamics (Equation ) is asymptotically stable if A + L p is Hurwitz …”

SummaryThe active disturbance rejection control of a delayed 2-degree-of-freedom structure against earthquake motion force is investigated. A shaking table that resembles the acceleration profiles of most known earthquakes is used to generate the horizontal force. To compensate the motions caused by the earthquake simulator, an active tuned mass and damper system is attached to the structure. Due to the strong effects of the motion forces as a disturbance input, an active disturbance rejection controller including an extended state observer is designed and implemented. The controller designed is modified with including a state predictor to address the control input delays induced by the remote networked control or actuator delays. The stability of the whole system is verified via Lyapunov analysis and tested on the structure sample including shaking table. The results show the effectiveness of the proposed approach to regulate the structure motions in different earthquake scenarios.

“…in Ahmed-Ali, Cherrier, and Lamnabhi-Lagarrigue (2012). In Najafi, Hosseinnia, Sheikholeslam, and Karimadini (2013), this approach is used for linear systems to generate a control law by means of a chain of predictors when the full-state information is accessible with a constant delay. The difficult step is to extend the chain approach to the case of timevarying delays.…”

This paper concerns the problem of the control of linear systems by means of feedback from delayed output, where the delay is known and time-varying. The main advantage of the approach is that it can be applied to systems with any delay bound, i.e. not only small delays. The predictor is based on a combination of finite-dimensional elementary predictors whose number can be suitably chosen to compensate any delay. The single-predictor element is an original proposal, and the class of delays to which the schema can be applied includes, but it is not limited to, continuous delay functions.
