    摘要: A control apparatus for a vibration type actuator is disclosed, with which at least three kinds of vibrations are excited, and a desired motion can be carried out with high efficiency. The vibration type actuator includes a rotatable moving member, an elastic member contacting the moving member, and an electro-mechanical energy conversion element exciting at least three different kinds of vibrations in the elastic member by supplying at least three periodic signals having different phases. The control apparatus includes a rotation axis determining unit, a parameter determining unit and a control circuit. The rotation axis determining unit determines a rotation axis for rotating the moving member. The parameter determining unit determines, by using an inverse model, phase and amplitude of the periodical signals.

    摘要: A vibration-type driving device comprises a vibration element including a driving member and an electro-mechanical energy conversion element having an electrode and arranged to displace the driving member with a driving signal supplied to the electrode, and a driven element that is kept in contact with the driving member of the vibration element. According to the driving signal supplied to the electrode of the electro-mechanical energy conversion element, the vibration element excites vibrations in two flexural vibration modes in which a direction of generation of a node in one mode is perpendicular to that in the other mode. With the use of the two flexural vibration modes, the natural vibration frequency of the vibration element can be prevented from increasing, and the position of a node occurring in one flexural vibration mode and the position of an antinode occurring in the other flexural vibration mode can be made to coincide with each other, so that the amount of displacement of the driving member can be made large.

    摘要: Provided is a driving system for a vibrating type actuator capable of simplifying a driving circuit. A vibrating body of the vibrating type actuator can generate a first mode and a second mode which are different in a vibration form, in accordance with an alternate current signal to be supplied. An alternate current signal having a frequency close to a resonance frequency in the first mode or the second mode is applied either between an electrode Va and a common electrode Vc or between an electrode Vb and the common electrode Vc of the vibrating body of the vibrating type actuator. One of the electrodes to be supplied with the alternate current signal is selected by a switching element operated based on a signal from a driving direction switch.
