This paper proposes an asymmetric acceleration drive method for linear oscillatory actuators under open-loop control. The effectiveness of this method is confirmed through the comparison of the 3-D FEM analysis results with the measurements of a prototype. Streszczenie. W artykule przedstawiono asymetryczne urządzenie oscylacyjne dla liniowych aktuatorów ze(More)
Recently, a high-quality image has been obtained by a video camera because of its improved imaging performance. However, image quality deteriorations due to vibration have become a problem. In order to solve this problem, various image stabilization technologies have been developed. A lens-unit-swing system which consists of a lens and an imaging device is(More)
This paper proposes a simplified position estimation method and clarifies the dynamic characteristics of the two-degree-of-freedom (DoF) resonant actuator under sensorless control. The feature of this two-DoF actuator is that movement in the x- and z-axis can be independently controlled by vector control. In this paper, we extrapolate the mover position(More)
The asymmetric acceleration waveform shown is not necessarily the best waveform since it has not been optimized. In this paper, first, how the properties of the asymmetric acceleration properties are related to haptic perception is investigated by conducting experiments on volunteers. Then, by applying a genetic algorithm to the optimization method, an(More)
Mobile haptic devices are being studied extensively as they have a great potential to be used as information transfer devices. Amemiya and Maeda proposed a method for haptic feedback by a linear oscillator using asymmetrical drive. We have then proposed a small two degree-of-freedom oscillatory actuator for application as a haptic device. Using this(More)
