    • According to a preferred aspect of the instant invention, there is provided a system and method of robust vibration suppression which might be used in many subject matters, but which is preferably used in connection with computer controlled electromechanical devices such as disk drive arms. In a first preferred embodiment, a Gaussian waveform is selected as a velocity profile, with its integral and derivatives providing position and acceleration/jerk profiles respectively. According to another preferred embodiment, the movement velocity profile will be selected to be a member of the prolate spheroid family of waveforms. This family of functions has certain optimal properties with respect to the frequency domain concentration of energy for a given time-domain length time series. The movement of a flexible arm that is performed according to the invention will be one that has minimal or reduced residual vibration after it has reached its destination.
    • 根据本发明的优选方面,提供了可用于许多主题的鲁棒振动抑制系统和方法,但是优选地与计算机控制的机电装置如磁盘驱动臂结合使用。 在第一优选实施例中,选择高斯波形作为速度分布,其积分和导数分别提供位置和加速度/加加曲线​​。 根据另一个优选实施例,移动速度分布将被选择为波形的长椭球系列的成员。 对于给定的时域长度时间序列,这个函数族对于能量的频域浓度具有一定的最佳性质。 根据本发明执行的柔性臂的运动将是在到达目的地之后具有最小或减小的残余振动的运动。
