Event-triggered fault tolerant control for a class of state saturated systems subject to deception attacks

Abstract

This study is concerned with event-triggered fault tolerant control for a class of state-saturated systems subject to stochastic faults, unknown but bounded disturbances and deception attacks. After formulating stochastic faults, state saturations, and deception attacks, a hybrid system model is developed to facilitate analysis and design. An event-triggered transmission mechanism is proposed to decide whether the measurement values should be sent to the controller via wireless network. Since the sensor data is attacked by the adversary during the transmission, the actual measurement value received by the controller needs to be recalculated. Expressions of the dynamic output feedback controller are presented, and criteria are used to design a dynamic feedback controller to ensure that the system is uniformly ultimately bounded. To deal with the current problem, an algorithm is also developed and tested using the linear matrix inequality (LMI) toolbox. Finally, two numerical examples are given to illustrate the validity and effectiveness of the proposed strategies.

Event-triggered consensus control of second-order nonlinear multi-agent systems under denial-of-service attacks

“…Moreover, we have shown that there is no Zeno behaviour exhibited. Our future research will focus on the nonlinear MASs under other types of attacks, such as deception attack (Gao et al, 2020) and false data-injection attack (Li et al, 2020).…”

Adaptive event-triggered control for master-slave switched systems subject to attacked state-dependent switching law

“…By this scheme, the sampling and transmission of data is determined by a predefined performance dependent event-triggering condition and only necessary signals will be sent out. Event-triggered control has been investigated widely and many effective schemes are presented (Gao et al, 2020;Li et al, 2018;Qi et al, 2019aQi et al, , 2020bZhao et al, 2020). For example, a hybrid-triggering scheme which can be described by a Bernoulli variable is studied in Liu et al (2018).…”

Event-triggered adaptive control of a class of nonlinear systems with non-parametric uncertainty in the presence of actuator failures

“…In fact, the control system may show a desirable performance many times without updating the control signal. This issue is very important in networked control systems (Gao et al, 2020;Shi et al, 2018), in which there is a network for communication between the sensors and actuators. Such a communication network (with a limited bandwidth) is shared between some system nodes.…”
