Latest Patents
Jiajun Song holds a patent for "Multi-resonant feedback control of a single degree-of-freedom wave energy converter." This invention introduces a multi-resonant wide band controller that decomposes the control problem into manageable sub-problems. Each sub-problem is addressed by an independent single-frequency controller, allowing for individual optimization. The feedback control mechanism enables real-time implementation of multi-frequency complex conjugate control, relying solely on measurements of the buoy's position and velocity. Notably, this approach does not require knowledge of excitation forces, wave measurements, or wave predictions. The feedback signal processing can be efficiently executed using Fast Fourier Transform with Hanning windows, optimizing amplitudes and phases. This method simplifies control implementation while generating energy comparable to complex conjugate control, showcasing its effectiveness.
