An improved negative zero vibration anti-swing control strategy for grab ship unloader based on elastic wire rope model
A dynamic model of swing system of bridge-type ship unloader is established by considering the elastic factor of wire rope in this paper. Based on this model, an improved Negative Zero Vibration (NZV) shaper with optimal control parameters of variable rope length system is proposed to restrain the s...
