Analytical analysis and oscillation control of payload twisting dynamics in a tower crane carrying a slender payload
Mechanical Systems and Signal Processing（2021）
Abstract
•Model of tower cranes carrying slender payloads is derived.•Equation for estimating the twisting frequency is presented.•A discontinuous piecewise smoother is proposed for controlling swing and twisting.•Experiments validate dynamic behaviour and the control effectiveness.
