Robust Adaptive Fault Estimation Observer-Based FTC Design for Time-Delay PEMFC Systems
https://orcid.org/http://orcid.org/0000-0001-5411-1310
This work develops fault tolerant control (FTC) design based on robust adaptive fault estimation observer (RAFEO) for proton exchange membrane fuel cell systems (PEMFCSs) with time-delays. The robust adaptive fault estimation algorithm (RAFEA) is used for improving speed and accuracy of fault estimation. It is proposed using linear matrix inequality (LMI) technique for increasing system efficiency. It ensures stability and enhances faulty system efficiency. An actuator stuck fault is considered in which faulty input signals are constantly blocked. Time-delay is considered in deriving both RAFEO and FTC algorithm which is not incorporated in previous works on PEMFCSs. Simulation results show efficacies of proposed design methods in application to cathode pressure model of the system.
