Abstract :
A high speed precision positioning system is developed through rotary voice coil actuator (VCA) direct driving. By use of finite element analysis (FEA) and dynamic simulation method, the dynamic characteristics of the motion system are investigated, and the magnetism distribution around the VCA has also been acquired. Considering the remnant vibration during the high-frequent starts and stops as well as the friction during the motion process, traditional PID control and error compensation theory are adopted, in addition, the bang-bang control theory has been utilized in order to accomplish time optimal control of the motion system. The precision control of the system has been realized by use of Composer.
