Conclusions, Open Lines and Further Reading

This chapter summarises the main results presented in the book, regarding the application of Second-Order Sliding-Mode algorithms for robust control of autonomous PEM fuel cells. Several improvements to the existing control schemes and many open directions of research are proposed. Most promising issues are related to Adaptive Super-Twisting algorithms, Higher-Order Sliding-Mode MIMO Control, Model Predictive Control, and Sliding-Mode Observers for internal Fuel cell variables. As further issues related to fuel-cell-based systems, hybrid standalone systems and distributed generation systems are regarded as appealing fields for future improvements.
