Fault detection for vehicle active suspension systems in finite‐frequency domain

Event‐triggered distributed fault detection over sensor networks in finite‐frequency domain

“…Finally, an F ‐404 aircraft engine system example has been applied to confirm the effectiveness of the proposed fault detection approach. The future research topics would be the extension of the main results obtained in this paper to the system with various communication protocols [35–37], fault tolerant control [38], various practical engineering systems [39], the system with probabilistic constraints [40].…”

Zonotopic fault detection observer design for discrete‐time systems with adaptively adjusted event‐triggered mechanism

“…Theorem 3: Give scalars γ 1 > 0, γ 2 > 0, 0 < α < 1, κ 1 , κ 2 , β, preselected matrix S, diagonal matrix Ω, and finite frequency ranges. Under event-triggered communication mechanism (3), the residual system (5) is asymptotically stable with the L ∞ performance (6) and the H_ performance (7) if there exist symmetric matrices P 1 > 0, P 2 , Q > 0, invertible matrix X, and general matrices…”

“…In practice, control systems will inevitably suffer from failures caused by loss effectiveness of actuators or sensors and so on [1][2][3][4][5][6][7][8][9][10]. Consequently, fault diagnosis and fault-tolerant control have gained much attention from researchers during the last few years since the increasing requirements for security and reliability of practical systems including aerospace system, wind energy conversion system, power system, chemical process and so on [11][12][13][14][15][16][17].…”

Fault detection for a class of uncertain Lipschitz systems with time delays in finite‐frequency domain

“…The finite‐frequency domain fault sensitivity and disturbance robustness conditions are given by considering GKYP lemma and LMI technique. In [21], an FD approach for a vehicle active suspension systems in low‐/middle‐/high‐frequency ranges is proposed. By GKYP lemma and stability method, three FD filters are designed in different frequency domains.…”
