Motion Control of a Two-Degree-of-Freedom Linear Resonant Actuator without a Mechanical Spring
Sensors, 2020 This study aims to present a new two-degree-of-freedom (DOF) linear resonant actuator (LRA) and its motion control method without a position sensor. The design method of 2-DOF LRA which resonates with only detent force without a mechanical spring is ...
