An output-feedback adaptive control architecture for mitigating actuator attacks in cyber-physical systems
Yadegar, Meysam; Meskin, Nader; Haddad, Wassim M. ( John Wiley and Sons Ltd , 2019 , Article)In this paper, we present a control design framework wherein an adaptive-based corrective signal is augmented to the output of the nominal controller in order to suppress or counteract the effect of malicious actuator ... -
Data-driven fault detection and isolation of nonlinear systems using deep learning for Koopman operator
Bakhtiaridoust, M.; Yadegar, Meysam; Meskin, Nader ( ISA - Instrumentation, Systems, and Automation Society , 2023 , Article)This paper proposes a data-driven actuator fault detection and isolation approach for the general class of nonlinear systems. The proposed method uses a deep neural network architecture to obtain an invariant set of basis ... -

Fault-tolerant control of non-linear systems based on adaptive virtual actuator
Yadegar, Meysam; Afshar, Ahamad; Meskin, Nader ( Institution of Engineering and Technology , 2017 , Article)A new adaptive fault-tolerant control architecture for Lipschitz non-linear systems is developed. Specifically, the proposed approach involves a novel adaptive virtual actuator which is inserted between the faulty plant ... -
Observer-based tracking controller design for a class of Lipschitz nonlinear systems
Yadegar, M.; Yadegar, Meysam; Afshar, Ahmad; Davoodi, Mohammadreza ( SAGE Publications Inc , 2018 , Article Review)© 2017, © The Author(s) 2017. In this paper, the observer-based controller design problem for tracking a constant reference input in Lipschitz nonlinear systems is addressed. To this end, at first, a state feedback controller ... -
Reconfigurable control of linear systems based on state feedback adaptive virtual actuator
Yadegar, Meysam; Meskin, Nader; Afshar, Ahmad ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)In this paper, design and development of fault tolerant control (FTC) of linear systems subject to loss of effectiveness and time-varying additive actuator faults as well as an external disturbance using the fault-hiding ...
