Simultaneous H/H fault detection and control for networked systems with application to forging equipment

Event‐Triggered Fault Detection for Networked Control Systems Subject to Packet Dropout

“…However, as shown in [27], there exists a methodology for representing any sensor faults in the form of an actuator fault. Indeed, given the system described by (1), it is possible to augment the state and output equations by one additional state. This auxiliary state describes the behavior of the sensor fault and in the new output equation, the sensor fault vector is not appeared while it is modeled as an additive term in the state equation and can therefore be treated as an actuator fault.…”

“…However, it should be noted that the application of our proposed methodology is not restricted to this system and can be easily considered for numerous other classes of engineering systems such as chemical processes, manufacturing systems, power networks, oil and gas systems, and industrial electronic equipment. Indeed, the considered system in (1) is quite general and the linearized model of many industrial and engineering systems in the presence of external disturbances and faults can be expressed according to (1). Hence, our methodology which is based on the general model in (1), can be applied to problem of event-triggered fault detection for different industrial applications.…”

$H_2$ /$H_\infty$ Simultaneous Fault Detection and Control for Markov Jump Linear Systems With Partial Observation

“…The work [22] presented a solution based on LMI using the performance index H − /H ∞ . The authors in [26] proposed an SFDC for continuous-time MJLS applied to a forging equipment. [14] presented an SFDC for continuous-time MJLS considering uncertain transition rate in the Markov chain.…”

Simultaneous fault detection and antisaturated control based on dynamic observer for inverted pendulum control system

“…The problem of simultaneous fault detection and control (SFDAC) unifies the control and the detection units into a single unit, thus reducing the overall complexity. Also, this research field has received a lot of attention in the last two decades . The problem of fault detection for continuous‐time switched systems under asynchronous switching was investigated by Du et al The robust fault‐detection filter design problem for uncertain linear time‐invariant (LTI) systems with both unknown inputs and modeling errors was studied by Zhong et al The SFDC problem was formulated as a mixed H 2 / H ∞ optimization problem, and its solution is presented in terms of two coupled Riccati equations.…”
