Passive Fault Tolerant Control of PEMFC air feeding system

International audienceFuel cells are powerful systems for power generation. They have a good efficiency and do not generate greenhouse gases. This technology involves a lot of scientific fields, which leads to the appearance of strongly inter dependent parameters. This makes the system particularly hard to control and increases fault's occurrence frequency. These two issues call for the necessity to maintain the system performance at the expected level, even in faulty operating conditions. It is called " fault tolerant control " (FTC). The present paper aims to give the state of the art of FTC applied to the proton exchange membrane fuel cell (PEMFC). The FTC approach is composed of two parts. First, a diagnosis part allows the identification and the isolation of a fault; it requires a good a priori knowledge of all the possible faults. Then, a control part allows an optimal control strategy to find the best operating point to recover/ mitigate the fault; it re quires the knowledge of the degradation phenomena and their mitigation strategies

“…One of the few research on (A)FTC applied to PEMFC, have been done by Lebreton et al [14] [115] dealing with water management and air feeding system. They used a neural network to compute on line the new PID self tuning parameter values to recover the detected fault.…”

“…In addition, this strategy uses neither control reorganization nor fault detection and diagnosis (FDD). The paper in introduced a PFTCS based on an auto‐tuning PID regulator that is dedicated to air feeding system faults. Nevertheless, it is conservative and the fault‐tolerant adaptive capacity of the nonlinear system is limited.…”

This paper focuses on the problem of adaptive output feedback fault tolerant control for a nonlinear hydro-turbine governing system. A dynamic mathematical model of the system is established, which aims to investigate the dynamic performance of the model under servomotor delay and actuator faults. Then, a fault estimation adaptive observer is proposed to achieve online real-time diagnosis of system faults. Based on the online fault estimation information, an observer-based adaptive output feedback fault tolerant controller is designed. Furthermore, under reasonable assumptions, the results demonstrate that the closed-loop control system can achieve global asymptotic stability by Lyapunov function. Finally, the numerical simulation results are presented to indicate the satisfaction control effectiveness of the proposed scheme.

“…() Following a well‐established terminology, FTC approaches are classified into passive and active . The passive approaches use robust control theory to guarantee some fault tolerant capabilities . They are simple to design and implement, but are more conservative in terms of performances and allowable faults with respect to active approaches.…”

“…4 The passive approaches use robust control theory to guarantee some fault tolerant capabilities. 5 They are simple to design and implement, but are more conservative in terms of performances and allowable faults with respect to active approaches. On the other hand, these latter compensate the faults either by selecting a precalculated control law or synthesizing online a new control strategy.…”

Int J Robust Nonlinear Control. 2018;28:611–624, which has been published in final form at https://doi.org/10.1002/rnc.3888. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving.In this paper, a model reference fault tolerant control strategy based on a reconfiguration of the reference model, with the addition of a virtual actuator block, is presented for uncertain systems affected by disturbances and sensor noise. In particular, this paper (1) extends the reference model approach to the use of interval state observers, by considering an error feedback controller, which uses the estimated bounds for the error between the real state and the reference state, and (2) extends the virtual actuator approach to the use of interval observers, which means that the virtual actuator is added to the control loop to preserve the nonnegativity of the interval estimation errors and the boundedness of the involved signals, in spite of the fault occurrence. In both cases, the conditions to assure the desired operation of the control loop are provided in terms of linear matrix inequalities. An illustrative example is used to show the main characteristics of the proposed approach.Peer ReviewedPostprint (author's final draft
