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.

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.

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.

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.
