Control apparatus for vibration type actuator, vibration type actuator system, and method for controlling vibration type actuator |
摘要 |
<p>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.
