Description
Summary:Wave energy constitutes a crucial player in the future renewable energy mix. Within this field, model-based optimal control strategies have a fundamental role in minimising the associated levelised energy cost. Model-system discrepancies can compromise control performance. In particular, faulty conditions must be accommodated since they can severely affect control efficiency and device integrity. For this purpose, an FDI estimator-based optimal control reconfiguration strategy, capable of restoring optimality with sensor faults, is proposed. The technique is tested under nominal and faulty conditions, in representative operating scenarios, showing a remarkable capability to recover energy absorption performance even under severe measurement mismatches.
