A Modal Synergistic Actuation Multi-Degree-of-Freedom Rotary Piezoelectric Actuator Based on Mode-Shapes Spatial Position Control
{{output}}
Conventional multi-degree-of-freedom (multi-DOF) piezoelectric actuators realize 3D motion by coordinating several orthogonal physical axes (e.g., X/Y/Z). This reliance substantially inflates hardware and control complexity. Therefore, we propose a modal-syner... ...
