Traditional analysis and design for networked control systems (NCSs) with state quantization have been investigated under single wired/wireless network environment. This paper studies the quantized control of distributed event-triggered NCSs under hybrid wired–wireless networks environment. Unlike the most existing NCSs, the controller communicates with distributed sensors through multiple wired–wireless channels and the measured signals from sensors might suffer from communication constraints of hybrid wired–wireless networks, which makes the quantized control of distributed event-triggered NCSs more complex. To reduce the communication burden of each channel, a distributed event-triggered mechanism and multiple quantization scheme are firstly proposed. The communication characters of hybrid wired–wireless networks are then analyzed, which are described by different Markov chains. Furthermore, a novel system model is presented, and a sufficient condition of the stochastic stability is derived. The relationship between the system stability criteria and the maximum hybrid wired–wireless network-induced delays, the event-generators parameters and multiple quantization parameters is established. Finally, simulation results confirm the effectiveness and feasibility of the proposed method. [ABSTRACT FROM AUTHOR]

Unlike the widely existing H 2 / H ∞ filtering methods under single (i.e., wired or wireless) network with single channel environment, there exist multiple event-generators and different network-induced delays in hybrid wired–wireless networks, which make H 2 / H ∞ filtering analysis and design more complex. The main objective of this paper is to investigate multiple event-triggered H 2 / H ∞ filtering for hybrid wired–wireless networked systems with random network-induced delays. For multi-sensor network communications, a multiple event-triggered mechanism is employed firstly, which can reduce communication burden of each channel. The different communication characters of hybrid wired–wireless networks are then described by two Markov chains, and a general filtering error dynamic system model with the event-triggered parameters and multi-channel network-induced delays of hybrid wired–wireless networks is presented. Furthermore, the designed filter enables the filtering error dynamic system to be stochastic stability and to achieve a prescribed performance, and the relationships between the stability criteria and the maximum network-induced delays of hybrid wired–wireless networks, the event-triggered parameters and the system performance parameter are established. Finally, simulation results confirm the effectiveness of the proposed method. [ABSTRACT FROM AUTHOR]

Highlights: [•] We introduce the noise-induced mechanism into the prisoner’s dilemma game. [•] Cooperation will be largely enhanced by introducing the noise into the calculation of fitness. [•] Despite the defectors prevail initially, the stressed factor still promotes the cooperation. [•] The mechanism studied here is helpful on different kinds of interaction networks.
