Robust decentralized actuator fault detection and estimation for large-scale systems using a sliding mode observer

Decentralised Observation Using Higher Order Sliding Mode Techniques

“…Remark 5 From the structure of the dynamical system (25)-(31) and the dynamical system (33), it is straightforward to see that the designed dynamics are decoupled and thus they are decentralised observers which compares favourably with the existing results (Sundareshan, 1977;Sundareshan and Elbanna, 1990;Pillosu et al, 2011;Yan and Edwards, 2008b;Yan et al, 2003).…”

“…A class of linear interconnected systems are considered in Sundareshan (1977) and Pillosu et al (2011) where the proposed observers are coupled together through networked interconnections and thus are not decentralised. Later, for a class of nonlinear interconnected systems, a variable structure observer is proposed in Yan et al (2003) and a first order sliding mode observer is proposed in Yan and Edwards (2008b) to enhance robustness to uncertainties. However, in both Yan and Edwards (2008b) and Yan et al (2003), interconnection terms are employed in the observer design and thus the designed observers are not decentralised.…”

Decentralised observers are proposed for linear large scale systems in Gopal and Ghodekar (1985) where it is required that the interconnections can be reconstructed by dynamical systems.…”

Decentralised control for complex systems - an invited survey

“…A variable structure adaptive fuzzy logic control approach for designing a decentralised controller for load frequency control of interconnected power areas in El-Metwally (2010) to improve the dynamic performance of the frequency and tie-line power flow under a sudden load change in the power areas. In addition, decentralised control has been applied to other practical systems such as a coupled inverted pendulum system Yoo et al, 2009;Li et al, 2011), wind turbine (Wu et al, 2008), vibration isolation system (Kim et al, 2001), a platooning vehicles system (Yan and Edwards, 2008;Ghasemi et al, 2013), river pollution control (Mahmoud and Hassen, 1986), chemical process control (Hudon and Bao, 2012;Zhang et al, 2013;Lunze, 1992), satellite attitude control (Wu et al, 2012) and flight control (Vukobratovic and Stojic, 1986;Boskovic and Mehra, 2010) to name a few. In recent years, decentralised control strategies have been employed in bio-engineering systems (Sato et al, 2012;Nekoukar and Erfanian, 2012).…”

Entwurf robuster modellbasierter Fehlerisolationsfilter

“…Die explizite Berücksichtigung von Robustheitsaspekten erfolgt unter anderem in [72,157,213,215]. Weiterführende Ergebnisse erlauben darüber hinaus beispielsweise die Anwendung auf linear parameterveränderliche Systeme [5], Klassen nichtlinearer Systeme [37] sowie die Fehlerdiagnose in dezentralen [267] und stochastischen [82] Systemen und Erweiterungen auf fehlertolerante Regelungen [64].…”
