Abstract
A method for controlling movement of a movably mounted body (14) of a mechanical system (2, 56, 62). The mechanical system (2, 6, 62) includes a drive unit (4, 64), which is operated by a medium, and also a control valve (20, 22). The movably mounted body (14) is driven by the drive unit (4, 64). A drive movement of the drive unit (4, 64) is controlled with the aid of the control valve (20, 22). In order to avoid or reduce excitation of undesired vibrations in the mechanical system (2, 56, 62), it is proposed that the control valve (20, 22) be actuated using a control signal (u(t)) which comprises a first and also a further switching pulse (S1, S3) each having a prespecified pulse duration. The pulse duration of the first switching pulse (S1) is equal to the pulse duration of the further switching pulse (S3). A time difference (Δt1-3) between the start of the first pulse (S1) and the start of the further switching pulse (S3) is matched to a natural period duration of the mechanical system (2, 56, 62).
