Abstract
When installing a servo linear electric drive on platforms with supports of passive vibration isolation during positioning, elastic vibrations occur with the natural frequency of the elastic platform. The features of the velocity profile of such an electric drive with the ability to limit the jerk are considered. A mathematical model and a structural diagram of an elastic system are presented. When simulating such a system, the dependences of overshoot on the relative period of vibrations were obtained. It is shown that the optimal jerk time - from the point of view of minimizing the overshoot - is its value equal to the period of the 1st resonance of the "elastic" platform. The calculation of the minimum value of the displacement, at which the efficiency of the choice of the optimal value of the jerk, is ensured. The proposed choice of the optimal jerk time is confirmed by the experimental study.
