One of the mayor challenges facing current society is to transform its energy model, allowing for secure, affordable, and efficient energy. The search for new energy sources with a minimal impact on the environment has brought about new complex technical solutions that require novel control algorithms in their path to commercialization.

This special issue aims to increase the performance and reliability of complex clean energy devices, subsystems, and processes by developing control solutions based on alternative approaches. The articles should provide controls that improve the performance and reliability of complex devices or components targeting clean energy. Contributions containing research to predict, diagnose, monitor, and manage the state or condition of engineering assets using various advanced controls are encouraged.

The overarching intention of this special issue is to publish new progress dealing mainly (but not exclusively) with state-of-the-art control applications that have been used for different clean energy technologies. This may include methodological themes as chaos, genetic algorithms, cellular automata, neural networks, and so on. Submissions relating to fusion, ocean energy, or offshore wind energy are especially encouraged. Technical control solutions for advanced complex clean energy system designs (monitoring, control, online communication, integration, etc.) leading to an efficiency improvement will be considered in this issue. Review articles may also be submitted. Papers integrating conceptual themes and applications that cross traditional disciplinary boundaries are welcome.

Potential topics include but are not limited to the following:

• Intelligent/robust control for complex models in fusion energy
• Cellular automata based control for offshore wind energy
• Complex control solutions on ocean energy
  • Wave energy
  • Tidal energy
  • Salinity gradient energy
  • Ocean thermal energy
