“…In particular, the importance of this estimation to ensure the system evolves within the modeling region, where the control law parameterization is valid, has been illustrated. Future directions for this work include the extension of the proposed method for the case of time‐varying parametric uncertainties and the application to event‐triggered control 46‐48 of nonlinear networked control systems.…”

Robust stabilization of a class of uncertain nonlinear systems through a sampled-data control law is considered in this work. Based on the forward discrete-time Euler approximation, conditions in the form of linear matrix inequalities are provided to synthesize a discrete controller that guarantees the states to be asymptotically driven to the origin, regardless of the presence of bounded parametric uncertainties. In contrast with other approaches, the system is not required to be Lure-type nor the conditions to have predefined gains to be tested. Examples are given to illustrate the effectiveness of the proposal.

“…For instance, co-design conditions have been proposed for CETC of LTI systems subject to input saturation 12 and Lur'e-type systems; 13 for CETC with time-regularization of LTI systems, 5,10,11,14 linear systems with cone-bounded nonlinear inputs, 15 and systems with slope-restricted nonlinearities; 16 for PETC of LTI systems, 17,18 Takagi-Sugeno (TS) fuzzy models, [19][20][21][22] and for linear switched systems with input saturation. 23 However, all the aforementioned papers on ETC co-design are limited to static ETMs, which are generally less efficient in managing communication resources than dynamic ETMs.…”

This paper addresses the dynamic periodic event‐triggered control for local stabilization of nonlinear networked control systems with communication delays. Based on a polytopic quasi‐linear parameter‐varying (quasi‐LPV) model of the nonlinear plant and the Lyapunov–Krasovskii stability theory, a local stability analysis condition is established. Then a constructive co‐design condition is proposed to jointly design the state‐feedback control law and the trigger rule. The local asymptotic stability of the closed‐loop equilibrium point of interest is ensured with a guaranteed region of attraction where trajectories remain inside even in the presence of communication delays. An optimization procedure is proposed to perform the co‐design considering the objectives of enlarging the guaranteed region of attraction and reducing the number of transmissions. Numerical examples indicate a trade‐off between these two objectives. Also, the examples illustrate the effectiveness of the proposed dynamic event‐triggered control co‐design approach over both its static counterpart and periodic time‐triggering mechanisms.

“…Networked control system (NCS) has gained great attentions during the past decades and it is applied widely in realtime industrial control, environmental monitoring, military, telemedicine and other fields [1]- [4]. The stability analysis and controller design for NCS with time-delay and data packet dropout has become a hot research filed on account of its essential impact on modern control theory, and a great many literatures have been reported [5]- [7].…”

The two-mode-dependent controller design problem for networked Markov system with timedelay in both S/C link and C/A link is investigated in this paper. Two independent Markov chains are used to describe the time-delay in S/C link and C/A link. A two-mode-dependent state feedback controller is proposed that depends on both the S/C time-delay and the mode of the Markov controlled plant. The sufficient conditions on the stochastic stability of the closed-loop system are established. The design method of the controller is also proposed on condition that the transition probability matrices of S/C time-delay and mode of the controlled plant are completely known and partly unknown respectively. A numerical example is exploited to illustrate the effectiveness and superiority of the proposed method.
