Receding horizon pseudospectral optimal control for wave energy conversion

摘要: The present study introduces a real-time control algorithm for applications involving energy maximisation and subject to technological limitations. Development of Wave converters constitutes an actual topic research, in their designs fluid-interactions, particularly on controllability. Immersed WECs are fluid-interaction forces, generating unusual solicitations specific hydrodynamic equation, such as radiation force or excitation forces. Various strategies were recently developed more advance algorithms currently applied WECS, Model Predictive Control [1], Pseudospectral optimal [2]. Such strategies, capable maximizing the production while insuring respect path constraints, realistic applicable real conditions limitation aspects. This paper presents receding horizon type control, based pseudospectral approach problem resolution. Dealing with irregular waves fixed horizon, presented need work nonperiodic functions, implying change basis functions involved description state variables, namely half-range Chebyshev Fourier functions. Application is generic WEC, compared standard MPC algorithm.
