Staff View: System identification and control of the horizontal motion of a twin rotor multi-input multi-output system (TRMS)

System identification and control of the horizontal motion of a twin rotor multi-input multi-output system (TRMS)

Rescue helicopters are often required to hover in certain motion, and most likely to maintain in still-air position for lifting purposes. the vibration produced by a helicopter during still-air hovering creates complexity in the physical control by the pilot, especially in the horizontal motion. to...
