Dynamic Behavior Simulation and Model Predictive Control of Wave Energy Converter

In order to easily evaluate the effectiveness of the control strategy and the performance of the power generation system in a wave energy generation system, a simulation method for simulating the dynamic behavior of a wave energy conversion device (WEC) is proposed in this paper. The electric motor is used to simulate the real movement of WEC under the action of sea waves. In order to maximize the output energy, model predictive control is used to optimize the electromagnetic torque of the generator. The simulation was carried out in MATLAB/Simulink, and the results showed the effectiveness of the proposed wave energy conversion device motion simulation method and MPC control strategy, which provided a theoretical basis for the subsequent WEC semi-physical simulation experiment platform.
