In this technical note, constructive control techniques have been proposed for controlling feedforward nonlinear time-delay systems. The terms admit an incremental rate depending on the input or delayed input. Based Lyapunov-Razumikhin theorem and Lyapunov-Krasovskii theorem, delay-independent feedback controllers are explicitly constructed such that closed-loop systems globally asymptotically stable. An example is given to demonstrate effectiveness of design procedure.
This note presents a dynamic gain approach to the event-triggered tracking control for class of strict-feedback nonlinear systems. A novel shifting function is designed make initial error arbitrarily bounded, which significantly relaxes requirement on error. To achieve objective that does not exceed constraint after prespecified finite time, barrier Lyapunov and new reduced-order observer are constructed by using desired signal. Based proposed approach, an output feedback controller...
This study is concerned with the adaptive stabilisation problem for a class of large‐scale output‐constrained non‐linear time‐delay systems in strict‐feedback form. The investigative system satisfies more general growth condition and precise knowledge time delay not required to be known priori. Firstly, an observer designed by dynamic gain control design technique. Then, based on novel Lyapunov–Krasovskii functional, output constraints are satisfied stability closed‐loop achieved. Finally,...
In this paper, global state feedback and output stabilisation problems are considered for a class of time-varying lower-triangular nonlinear systems in any prescribed finite time. The terms admit an incremental rate depending on continuous function. Firstly, by introducing novel transformation consisting gain scaling the function time that grows unbounded towards terminal time, involved system is transformed into new one easily designing controller. Then based Lyapunov theorem choosing gain,...
This paper investigates the problem of leader–follower finite-time consensus for a class time-varying nonlinear multi-agent systems. The dynamics each agent is assumed to be represented by strict feedback system, where nonlinearities satisfy Lipschitz growth conditions with gains. main design procedure outlined as follows. First, it shown that equivalent conventional control multi-variable high-dimension Second, introducing state transformation, converted into construction two dynamic...
This brief investigates the output feedback tracking control problem for feedforward nonlinear systems subject to event-triggered input. Different from existing results, it is first time that an algorithm proposed based on relative threshold strategy. To estimate unmeasured states, a novel dynamic observer designed by using information of and signal. By low gain scaling technique, controller observer, which avoids celebrated forwarding construct approach. Based constructed gain, proved all...
Abstract This article addresses the global regulation by periodic event‐triggered output feedback control for a class of feedforward nonlinear systems. Particularly, considered systems suffer from parameter uncertainties and unknown measurement sensitivity, which entail integrating advanced compensation strategies within framework. To this end, time‐varying gain is devised to tackle uncertain nonlinearities as well sampling error. Subsequently, novel controller constructed based on delicate...
Microwave dielectric ceramics are employed in filters as electromagnetic wave propagation media. Based on additive manufacturing (AM) techniques, microwave ceramic with complex and precise structures can be fabricated to satisfy filtering requirements. Digital light processing (DLP) is a promising AM technique that capable of producing high accuracy efficiency. In this paper, monolithic made from Al2O3 TiO2, molar ratio 9:1 (0.9 Al2O3-0.1 TiO2), were by DLP. The difference the properties...
