Summary: This paper investigates jamming attacks on wireless networked control systems in the presence of exogenous disturbance. Specifically, control input packets are assumed to be transmitted over an insecure wireless communication channel from a controller to a remotely located linear plant. The likelihood of transmission failures on this channel varies with time due to the power of the jamming interference signal emitted by an attacker. The paper demonstrates that jamming attacks can compromise system stability under disturbance, even if the system is stable without disturbance. It also presents conditions under which stability can be achieved under jamming and disturbance. The results are illustrated using an example networked control system with a fading wireless channel.

Summary: This article considers the security control issue of nonlinear networked systems using an interval type-2 fuzzy modeling strategy. A stochastic scheduling strategy called Markovian communication protocol is introduced to coordinate the sensor transmission order in order to avoid communication congestion. An asynchronous observer is designed to estimate the unmeasured states via the hidden Markov model. Additionally, a comprehensive scenario on deception attack is considered, where attacks occur in both the sensor-observer and controller-actuator communication channels with different types of deception signals. Some sufficient conditions for ensuring the ultimately boundedness of the resulting closed-loop system are obtained using the slack matrix approach and stochastic analysis technique. Simulation results demonstrate the validity of the proposed protocol-based fuzzy control method.

Summary: This article investigates stealthy attacks on cyber-physical systems using the stochastic communication protocol (SCP) to avoid data collisions. The attack's stealthiness is measured by the Kullback-Leibler divergence, and the attack performance is measured by the corrupted error covariance. The proposed attack strategy takes SCP-introduced effects into account and uses incomplete measurement outputs at each time instant to construct an attack model. A nonconvex optimization problem is formulated to achieve the desired attack performance for a given stealthy level. Analytical expressions for the attack parameters are derived, and simulations and experiments are conducted to validate the proposed theoretical results.

Summary: This article discusses the consensus of networked underactuated robotic systems subject to fixed and switched communication networks. By developing novel event-triggered control algorithms, the convergence of active states, boundedness of passive actuators velocities, and exclusion of Zeno behaviors are guaranteed. For fixed networks, sufficient criteria are established for distributed event-triggered mechanisms with and without using neighbors' velocities, achieving a better tradeoff between communication load and system performance. In the case of switched networks, a sufficient criterion is established assuming a spanning tree in the network union. A distributed sampled-data rule is constructed for updating own and neighbors' estimated positions, reducing unnecessary control cost. Several examples with performance comparisons validate the efficiency and advantages of the theoretical results.

Summary: This paper studies the robust static output feedback control of discrete-time Markov jump systems where the mode of operation cannot be directly measured. By using linear matrix inequalities, the paper guarantees robust stability and provides an upper bound on the H-2 norm of the closed-loop system. Additionally, the design technique is linked to the bounded real lemma and can be extended to cover the robust polytopic case.

Summary: This paper proposes an emulation-based controller and transmission policy design procedure for nonlinear wireless networked control systems. The objective is to ensure system stability and given control performance while minimizing communication power. The controller is designed by ignoring the network, and threshold policies are used for transmission power. Two power control laws are investigated: constant power and power level inversely proportional to channel gain. The paper explains how to select waiting time, channel threshold, and power level to minimize communication power and achieve desired control objectives.

Summary: In this work, a state feedback output regulation method is proposed based on a classical stabilizing composite state feedback controller. The method of asymptotic power series expansion is applied to provide an approximate solution to the regulator equation. A time-continuous state feedback controller is designed by combining the Chang transformation approach and the low-gain feedback technique, resulting in a semi-global bounded output regulation. Additionally, dynamic and observer-based event-triggered control schemes are proposed to reduce control updates and cater to the practical scenario of unavailable system state information.

Summary: This paper considers a Stackelberg duopoly model in which two firms compete to maximize their market share. The firms offer a service/product to customers in different geographical regions. Each region has unique characteristics of service propagation. The spreading rate can be controlled and is influenced by the firm's investment. The paper aims to characterize the advertising budget allocation strategy for each firm in order to maximize its market share. A Stackelberg game model is proposed to capture the main effects of competition. The strong/weak Stackelberg equilibria of the game and the associated budget allocation strategy are provided. The conditions under which the solution of the game is the winner takes all are established, and numerical results are presented.

Summary: We propose two new optimistic planning algorithms for nonlinear hybrid-input systems with dwell-time constraints. The algorithms select input sequences for refinement and maintain the discrete mode constant until the required dwell-time is reached. The convergence rate guarantees provided depend on a novel complexity measure of the dwell-time constrained problem and have been validated through simulation results for an adaptive-quantization networked control system and a COVID pandemic model.

Summary: In this study, we investigate the communication between a controller and a nonlinear plant through a wireless erasure channel. We propose an event-based control strategy that stabilizes the plant while sporadically using the unreliable wireless network. Stability is ensured in a stochastic sense due to the possibility of packet loss. We compare the event-based policy with a baseline policy based on age of information and show how to design an event-based policy that achieves the same control performance with lower channel utilization.

Summary: This letter aims to design optimal and robust H-infinity fault detection filters for linear sampled-data systems. Convex design conditions are derived in terms of differential linear matrix inequalities (DLMIs) for optimal, time-varying, H-infinity fault detection filters. The results are specialized to recast the optimal filter structure into a time-invariant, internal model-based, observer formulation. Furthermore, the robust case is also tackled, where the plant is uncertain. An illustrative example is presented to demonstrate the effectiveness of the results compared to those available in the literature.
