查询词典 oscillation of a function

The acceleration profile of the crane motion is designed to induce minimum payload pendulation during transpo rt,while the deceleration stage is designed to ensure freed om of residual oscillation near the end of the transport,and to deliver the payload at the target point.The techniques induce payload pendulation at least one half ofan oscillation cycle or integer multiples during each of the acceleration and deceleration stages.Starr(1995)designed a symmetric two-step acceleration and deceleration profile to transfer a suspended object.The duration on the constant acceleration steps is assumed to be negligible relative to the period of the payload oscillation.A linear approximation method of the oscillation period is used to generate the two-step symmetric acceleration profile.
