Advanced passivity-based, aging-tolerant control for a fuel cell/super-capacitor hybrid system

Abstract

This paper proposes an advanced aging-tolerant control for a fuel cell/super-capacitor hybrid system applied to a commercial vehicle. The controller is designed with the Interconnection and Damping Assignment-Passivity-Based Control (IDA-PBC) method to solve the converters coordination problem, where the state-of-charge of the super-capacitors and all current limitations are considered into the non-linear controller. The aging of the fuel cell is estimated in real-time by an extended Kalman filter and is integrated in the controller in order to preserve the stability of the whole system. Finally, a hardware-in-the-loop platform based on an INTEL/ALTERA FPGA is designed in order to validate the real-time operation of the algorithms for a specific case study with a fuel cell vehicle.

Power Management of a Hybrid Micro-Grid with Photovoltaic Production and Hydrogen Storage

“…Moreover, the eMPC can be reconfigured on-line to take into account a modification of the power source topology in case of failure [23] or units (FC or El) commitment in case of power partitioning. In addition to this, on-line tuning parameters are also possible based on FC/El state of health founded on diagnosis/prognosis indicators [24].…”

“…[20]. Moreover, it is possible to take into account the architecture of the system in real time when the power electronic topology is reconfigured in case of failure [23] or units (FC or El) commitment in case of power partitioning, as well as to change the tuning parameters according to the FC/El state of health based on diagnosis/prognosis tools [24]. The performance of the PMS is assessed experimentally on a Power-Hardware-In-the-Loop (PHIL) test bench to confirm the effectiveness of the proposition.…”

System-on-Chip FPGA Devices for Complex Electrical Energy Systems Control

“…Because of their large number of components like PEM fuel cells, electrolysers associated with hydrogen tanks for long term storage [12], PV arrays and power converters, and because of emerging possibilities in terms reinforcement of reliability offered by multi-stack fuel cells and interleaved converters [13], modern fuel cell hybrid power systems can be considered as very complex. To cope with this complexity, controllers are rapidly evolving by including always more new functionalities such as power sharing [14] impedance spectroscopy for data-based diagnosis [15], prognosis and fault system control [16], as well as weather and power consumption forecasting.…”

It is worth mentioning that this plant is emulated in the DS1006 and DS5203 dSPACE boards [14]. All the corresponding blocks in Fig.…”

“…3 Finally, all the modules in dashed lines, both within the plant or within the SoC FPGA-based controller, are not present in the current study but can be included for next prospects, thus showing the high level of scalability of the presented SoC FPGA-based control framework. The complete Hw/Sw system represents a Hardware-In-the-Loop (HIL) platform to validate the algorithms in real-time [14]. The SoC FPGA architecture is composed of: Two PWM units, an acquisition unit of 6 ADCs and a Soft core base on a NIOS II.…”
