A Novel Emergent State Control Law for an Integrated Helicopter/Turboshaft Engine System [PDF]
Mathematical Problems in Engineering, 2014 A two‐layer robust control scheme is proposed to get a better response ability for emergency maneuvers of helicopter. Note that the power used in ascending flight is the main coupling between helicopter and its turboshaft engines; therefore vertical flight control is separated from conventional helicopter control loops and combined with fuel flow and ...
