Web17 de mai. de 2024 · A theoretical analysis and simulation of each scheme, their resulting waveforms and THD analysis is provided. The harmonic contents of each scheme for vHB, vAN, and vAB are analyzed and compared. The LSM control scheme provides better harmonic results of 10.83% at ma of 0.99. Both control schemes have better THD … WebClosed‐loop Higher Harmonic Control (HHC) has been demonstrated successfully on a dynamically scaled model of the three‐bladed CH‐47D Chinook rotor in the Boeing V/STOL Wind Tunnel. Vertical and in‐plane 3/rev hub forces were suppressed simultaneously, completely, and continuously as the model was “flown” throughout a wide test envelope …
