    摘要: The invention relates to an ultrasonic motor, comprising a large number of plate-shaped piezoelectric ultrasonic actuators (10), each having at least one friction element (18) arranged thereon, wherein an element (1) to be driven is associated with in each case one ultrasonic actuator or in each case one pair of ultrasonic actuators, and the ultrasonic motor furthermore has a housing and an electrical exciter device. According to the invention, the elements to be driven are moveable independently of one another, and each ultrasonic actuator or each ultrasonic actuator pair is arranged in a holder (2), wherein the holders are pressed against one another by means of housing side covers (3), and the friction elements of the ultrasonic actuators are pressed against a friction layer (50) of the corresponding element to be driven by means of an elastic interlayer (5), which is in contact with those peripheral faces of the ultrasonic actuators which are arranged opposite the friction elements, with the result that, overall, a cassette-like ultrasonic motor stack is produced.

    摘要: Provided is a control method for a contraction-type gel actuator that can control an action of the contraction-type gel actuator with high accuracy and can be used for position control or the like. The method for controlling a displacement in the thickness direction of the contraction-type gel actuator (10) having an effect of contraction in the thickness direction by applying a voltage between an anode (14) and a cathode (12) between which a gel (13a or 13b) which comprises a dielectric polymeric material is interposed, which comprises a step of performing a feedback control of an applied voltage (E), with a sampled value of a displacement (x) when the applied voltage (E) is made to act on the contraction-type gel actuator (10), on the basis of the following equation (1):

    in the equation:
    xd represents a target displacement of the contraction-type gel actuator;
    Ed represents an applied voltage with respect to the target displacement xd obtained by the linear approximation of the applied voltage and the displacement from a measured result of the displacement in accordance with the applied voltage of the contraction-type gel actuator; and
    kp represents a proportional gain.

    摘要: The invention relates to a device for controlling a capacitive charge, in particular a piezoelectric actuator (2). Said inventive device comprises a signal generator (6) which is used to control a first end step (1) which is used to produce a discrete signal on the capacitive charge. The invention is characterised by a second end step (3, 4) which is used to generate a continuous signal on the capacitive charge. A counter-coupling of a deviation of an actual discrete signal is produced by a continuous signal required on the capacitive charge.

    摘要: Provided is a control apparatus of a vibration-type actuator for generating an elliptical motion of contact portions by a common alternating current including a frequency determining unit for setting a frequency of the alternating current. The frequency determining unit sets the frequency of the alternating current for changing an ellipticity of the elliptical motion, within a frequency range such that ellipticity changing frequency ranges set for the vibrators are overlapped, and the ellipticity changing frequency ranges are set for the vibrators as frequency ranges between an upper limit and a lower limit, such that the lower limit is a maximum resonant frequency at a time of changing the ellipticity, and the upper limit is larger than the lower limit and is a maximum frequency for the relative movement of the driving member.
