摘要：AbstractThis paper presents a robust feedback model predictive control (MPC) strategy for a sea wave energy converter (WEC). The control objective is to maximise the energy output while reducing the potential risk of device damage subject to sea wave excitation forces as persistent external disturbance. The robust feedback MPC proposed in this paper has the following prominent advantages: (i) the robust feasibility and stability can be guaranteed. (ii) the robust MPC method does not rely on the real time wave prediction. These features can not only reduce the unit cost of energy generation but also increase the reliability of the MPC controller.
