Summary:
The control of the motion of a Wave Energy Converter (WEC) is a key factor for its wave power extraction capabilities. If a gyroscopic device is employed to get the reaction torque, the gyro self spinning speed is an additional control parameter of the system. To maximize the power harvest, the PTO stiffness, the PTO damping and gyro self spinning speed have to be tuned by a proper adaptive control algorithm.
In order to test such adaptive control the performance of an ISWEC device, with rated power of 3 kW and located in the Alghero site (Mediterranean Sea), is simulated, with different float configurations, to derive a convenient design trade-off for the considered application.
