Abstract: This paper presents a new type of micro manipulator driven by magnetic force. The principle of a single freedom micro manipulator is introduced. The control system of the micro manipulator is researched, which consists of displacement sensor, electro magnet, driver circuit, A/D and D/A cards. Intelligent control method of dual CMAC is put forword.The control program is compiled with C++ and Matlab language. The experiment result indicates that the system can meet the control requirement for the maqnipulator movement.
