Open-Loop Control of Voice Coil Motor With Magnetic Restoring Force Using High-Low Frequency Composite Signals

This study proposed an approach to control voice coil motors (VCMs) installed in smartphone modules as autofocus actuators. The VCM developed in this study comprises guide rods. The magnetic field attraction force between guide rods and movable parts serves as lens restoring force. This study did no...
