“…We discussed only the x axis drive in this paper. However, we already reported that the proposed actuator can move x and z axis without interference [7]. Considering the results, the z axis will drive using same method.…”

“…Linear oscillatory actuators that have multi-degrees-of-freedom have been designed recently [1][2][3][4][5]. We proposed a two degree-offreedom (DoF) resonant actuator where both axes can be independently driven under vector control, and also a coupled analysis method for analyzing its dynamic characteristics by combining magnetic field analysis with electric circuit analysis, control method, and motion analysis [6][7].…”

The dynamic characteristics of a proposed two degree-of-freedom (DoF) actuator under amplitude feedback control are investigated in this paper. The feature of our proposed two DoF resonant actuator is that movement in the xand z-axes can be independently controlled by vector control. Two controllers: a PID controller and a proxy-based sliding mode (PSM) controller were compared for amplitude feedback control. A simulation model using finite element method (FEM) and MATLAB/Simlink is made, and the dynamic characteristics of the actuator under feedback control are calculated. Moreover, measurements on a prototype are conducted to show the validity of the simulation results.

“…In order to broaden the application range of LRAs, various kinds of multi-degree of freedom (DOF) resonant actuators have been developed [6,7]. Authors have also proposed a two degree-of-freedom resonant actuator that was able to be independently driven in x-and z-axes by vector control [8][9][10]. Additionally, authors have designed a three-DOF resonant actuator driven by conventional vector control [11].…”

This paper presents a novel vector control method for three-degree-of-freedom resonant actuator in order to improve its controllability. The effectiveness of the presented method is verified through electromagnetic field analysis using 3-D finite element method: Issue: A three-degree-of-freedom resonant actuator has a great potential to broaden the application range of linear oscillatory actuators because it has a lot of advantages: high efficiency, simple structure, etc. However, this actuator has low controllability because the magnetic structure of each axis is not independent. Aim: To establish a novel vector control technique suitable for our actuator. Materials and methods of the studies: Electromagnetic analysis employing 3-D finite element method. Results: In this study, the novel vector control theory was constructed on the basis of four-phase system. The new dq model was achieved by considering 3-D coordinate transformation. The proposed method is able to decrease the influence of thrust interference from other axis and achieved higher controllability. Conclusion: The results of the study will contribute to a practical use of the three-DOF resonant actuator.
