Published in 2019 at "Asian Journal of Control"

DOI: 10.1002/asjc.2022

Abstract: This paper considers the problem of fault detection and reconstruction of actuator faults for linear parameter varying descriptor systems. A polytopic sliding mode observer (PSMO) is constructed to achieve simultaneous reconstruction of LPV polytopic descriptor… read more here.

Published in 2021 at "International Journal of Robust and Nonlinear Control"

DOI: 10.1002/rnc.5745

Abstract: This article studies asynchronous switching for a class of switched descriptor systems (SDSs) under multiple event‐triggered schemes (ETSs). First, by using a mode‐dependent coordinates transformation, a SDS is equivalently transformed into a reduced‐order ordinary switched… read more here.

Published in 2024 at "Circuits, Systems, and Signal Processing"

DOI: 10.1007/s00034-024-02617-1

Abstract: In general, the construction of observers for nonlinear descriptor systems depends on the solvability of a linear matrix inequality involving system matrices, and it is based on the system’s nonlinearity. Therefore, the type of nonlinearity… read more here.

Published in 2020 at "IFAC-PapersOnLine"

DOI: 10.1016/j.ifacol.2020.12.2482

Abstract: Abstract We present a method for the certification of algorithms that approximate the L∞- or H∞-norm of transfer functions of large-scale (descriptor) systems. This certification is needed because such algorithms depend heavily on user input,… read more here.

Published in 2021 at "ISA transactions"

DOI: 10.1016/j.isatra.2021.03.037

Abstract: Several methods to improve stabilization conditions of Takagi-Sugeno fuzzy descriptor systems (TSFDS) are presented. First, we prove that with a modified non-quadratic fuzzy Lyapunov function and a PDC controller, stabilization problems of TSFDS are reformulated… read more here.

Published in 2017 at "Iet Control Theory and Applications"

DOI: 10.1049/iet-cta.2015.1143

Abstract: This study investigates the problem of reconstructing actuator faults for descriptor systems via a PD-type learning observer. By synthesising the derivatives of the output estimation error into the P-type learning law, a novel PD-type learning… read more here.

Published in 2018 at "Iet Control Theory and Applications"

DOI: 10.1049/iet-cta.2017.1408

Abstract: Sensor fault detection of discrete-time descriptor systems with bounded disturbances is studied. The authors propose a new structure of a fault detection observer by augmenting the output, which can broaden the application scope. A H… read more here.

Published in 2017 at "International Journal of Systems Science"

DOI: 10.1080/00207721.2016.1173264

Abstract: ABSTRACT We propose an adaptive distributed algorithm for distributed observers of linear time-invariant descriptor systems. In the proposed algorithm, the interconnection gains of the resulting distributed unknown input observers are adjusted adaptively and the adaptation… read more here.

Published in 2025 at "International Journal of Systems Science"

DOI: 10.1080/00207721.2025.2514590

Abstract: This paper investigates the challenge of reduced-order adaptive observer design for nonlinear rectangular descriptor systems. Nonlinearities satisfying incremental quadratic constraints are explored that cover Lipschitz, one-sided Lipschitz, monotone, and many other nonlinearities. The complexity of… read more here.
