Título del libro: Ccta 2020 - 4th Ieee Conference On Control Technology And Applications Título del capítulo: Fault-Tolerant Control for a Wave Energy Converter by Damping Injection
This work presents an active fault-tolerant control (FTC) scheme by
damping injection for a wave energy converter (WEC). The case study is
an Archimedes wave swing-based WEC, where two braking subsystems for the
floater play a critical role in protecting the physical structure from
extreme sea conditions. In order to obtain fault-tolerant behavior in
the presence of faults in the brakes, the deviation of the damping force
is compensated through the force produced by the linear generator, which
is controlled to maximize the energy conversion in nominal conditions.
For this purpose, the force deviation is estimated from a fault
detection and isolation (FDI) module by using an Utkin-based unknown
input observer, which is then used for the compensation that completes
the FTC. The proposed system is tested by numerical simulation under
different scenarios, including faults in the damping system and others.
The results demonstrate the capabilities and limitations of the
proposal, which achieves the established objective. The performances of
the nominal control and the proposed FTC are compared.
