Design and realization of automatic assembly workbench of voice coil;

In the high power loudspeaker design, how to design the lead wire diameter of a voice coil is a key problem.

A kind of automatic assembly workbench based on PLC and pneumatic for voice coil is expatiated in thispaper.

The system identification approach of Voice Coil Motor driving system based on labview software;

Structure Optimization Design of the Permanent Magnet Voice Coil Motor Based on 3D Magnetic Field Calculation;

Study of Active Vibration Control Based on Voice Coil Motor;

For a kind of 2-D high speed and precision positioning table driven directly by voice coil actuator,the dynamic control method was investigated to obtain good dynamic characteristic in case of high speed and high acceleration.

To improve the precision and efficiency of the integrated circuit (IC) package,a 2-DOF high speed and high precision XY positioning table driven by voice coil actuator is presented.

In order to overcome the limitation of speed and acceleration of the conventional two-dimensional drived xy precision positioning table with ball screw,a high-speed and high-precision xy positioning table based on voice coil actuator direct-drive,adopted novel flexible decoupling mechanism,was presented.

For the uncertain time-variant linear model of voice coil motor in micro hard disk servo control system,a nonlinear observer and its corresponding feedback controller with one saturation term are proposed by utilizing Lyapunov stability theory and linear matrix inequality.

Since friction force, inertia force, and airflow are the main factors to influence slider head, in this paper, on the basis of the classical model of voice coil motor, an uncertain nonlinear system is proposed by combining these facto.
