    摘要: Command path and command speed within a predetermined range are read. The predetermined range is time required for the object to move between two points on the command path. Speed command for each time is temporarily generated based on the read command path and the command speed. Frequency component that corresponds to mechanical vibration due to movement of the object and that is included in a speed command for the each time is calculated. Speed at which the frequency component becomes equal to or smaller than a preset reference value is determined as the permissible speed. Moving speed of the object is controlled so as not to exceed the calculated permissible speed.

    摘要: A closed-loop control structure for positioning a load with the aid of an electric motor includes a device for the active damping of unwanted, low-frequency vibrations. The closed-loop control structure has a position controller, a speed controller, and a current controller, which together, form a cascaded control loop. Damping signals which counteract unwanted, low-frequency vibrations are applied to the control loop, at least one first and one second damping signal of different phase angle being derived from a single sensor signal, and the first damping signal being injected between the position controller and the speed controller, and the second damping signal being injected between the speed controller and the current controller.

    摘要: In a holding arrangement (101) for a medical-optical instrument (103), an electric motor is provided in a rotational joint (111, 119) to compensate a load torque occurring in this rotational joint. This electric motor is supplied with current in correspondence to a detected position of the rotational joint (111, 119). A current control curve required for this purpose is stored in a memory. This current control curve can be determined in that the rotational joints are deflected with the electric motor into predetermined positions and the current demand needed therefor is detected. The holding arrangement (101) has a unit for actively damping vibration including a vibration damping control loop. This vibration damping control loop outputs a superposition motor current to the electric motor as an actuating quantity in order to move the rotational joint (111, 119) with the electric motor so that a detected vibration of the holding arrangement (101) is countered.
