Abstract: The disclosure relates to a drive means for non-resonant linear and/or rotary positioning of an object, comprising at least two piezoelectric or electrostrictive actuator groups, where-in a first actuator group moves a first runner portion relative to a stationary base of the drive means according to the principle of an inertia drive, and by means of the second actuator group a second runner portion is moved relative to the first runner portion with a limited range of movement in the high-resolution scan mode, wherein a common electrical control signal is applied to the first and second actuator groups.

Abstract: A method for controlling an inertial drive on the basis of pulse trains is disclosed. The pulse trains include pulses having sections of different gradients and having variable amplitude and/or frequency. A pulse interval occurs between the individual pulses, wherein the selected pulse duration is so short that is substantially less than the cycle duration of the natural oscillation of the system to be driven.

Abstract: A method is disclosed for controlling a linear or rotary multi-actuator drive device having a stationary and a movable part. Relative movement between the stationary and the movable parts is generated via actuators having limited strokes, which are in substantially continuous frictional contact with the movable part either directly or via a force-transmitting mechanism, wherein control signals having a timing offset are used therefor, which force alternation between the slip phase and the stick phase for each actuator.
