Abstract
A helicopter’s vertical takeoff and landing, as well as its ability to hover, make it ideal for carrying a suspended load, which facilitates multiple military and civil applications in places of difficult access. The suspended load; however, alters the flight characteristics and degrades the handling qualities of the helicopter, which can lead to instability or a serious accident. This work proposes a controller for a helicopter slung load system in low velocity forward fight. The controller uses explicit model following with command generator tracker to adhere to the Aeronautical Design Standard 33 specified level 1 handling qualities. A load stability control (LSC) term is added to dampen load oscillation. Simulations show that the addition of the LSC term improves the system behaviour by damping load oscillation. Results also show that the LSC has little effect on the desired helicopter response with only a small deviation from the target behaviour.
