摘要: This paper presents a contribution related to the control of nonlinear variable-speed marine current turbine (MCT) without pitch operating below rated speed. Given that operation MCT can be divided into several zones on basis speed, system objectives are different for each zone. To deal with this issue, we develop new approach based linear quadratic regulator variable generator torque. Our proposed enables optimization rotational speed turbine, which maximizes power extracted by and minimizes transient loads drivetrain. The novelty our study is use real profile from northern coasts Morocco. simulation results obtained using MATLAB Simulink indicate effectiveness robustness electrical mechanical parameters variations
