This article addresses the problem of stabilizing a continuous-time switched system affected by quantization and denial-of-service (DoS) attacks. The switching is assumed to be slow enough in the sense of combined dwell time and average dwell time, individual modes are assumed to be partly unstabilizable, and DoS attacks are supposed as energy limited by restraining DoS frequency and DoS duration. By introducing a Decision Maker into the system framework and proposing a switching algorithm for the attacked intervals, we simplify the design rules of the controller and divide the system status into four cases.On the basis of approximating the reachable set and analyzing the increasing/decreasing rate of Lyapunov function for each case, the sufficient conditions ensuring the exponential convergence and Lyapunov stability of the closed-loop system are obtained. Two examples are illustrated to demonstrate the effectiveness of the theoretical analysis.

This article studies output tracking control for switched systems with an adaptive stay interval based event-triggering scheme. By considering limited communication and computation resources, an event-triggering scheme based on stay interval is adopted. To further improve the adjustment capability of network communication, an adaptive stay interval which can be changed depend on system performance is presented. A class of tracking controllers with error integral terms are applied to make switched systems have more accurate tracking performance. Then, closed-loop switched systems that composed by system state and tracking error are modeled, and a set of sufficient conditions for ensuring systems achieve the desired output tracking performance is given. By using linear matrix inequalities, the controller gains and event-triggering parameters are obtained. In particular, since variable stay interval, triggering instants, and switching instants are mutually inclusive, various cases are fully analyzed to guarantee the integrity of system performance discussion. Finally, simulation examples are shown to demonstrate the feasibility.

Summary This article studies the quantized event‐triggered adaptive tracking control problem for a type of switched nonlinear systems with parameter uncertainties, where the corresponding control problem for each subsystem can be unsolvable owing to vanishing control gains at some points. A constructive design scheme is established by triple design of quantized event‐triggered adaptive controller of each subsystem and a switching dynamic event‐triggering mechanism dependent on quantization and a hysteresis‐type state‐dependent switching law. The developed scheme handles not only the asynchronous switching between candidate event‐triggered adaptive controllers and subsystems, but also the asynchronous switching between candidate quantizers and subsystems. Both the switching law and the event‐triggering mechanism do not cause Zeno behavior. As a special case, a sufficient condition to address the quantized event‐triggered adaptive control problem for the switched nonlinear systems is also derived under dwell‐time switching. Finally, the effectiveness of the developed schemes are verified by a numerical example and a networked one‐link manipulator with motor dynamics.
