Tóm tắt
The input shaping technique alters the human-operator commands to reduce the payload
oscillation. A single radial spring-damper can simultaneously produce three dampings to
suppress the tridirectional vibration of a crane payload. Combination of input shaping
and radial spring-damper can be a sensorless approach to reduce the vibration induced
by both operator commands and external disturbances. A numerical simulation of a boom
crane is carried out to clarify the effectiveness of each component in the combination. An
experiment of a laboratory boom crane is presented to show the effect of radial springdamper.
