In nanotechnology, nanowitlorung technology is the precondition and working foundation for the nanomeasurement and research of atom manipulation and its industrialization. A novel nanopeitioning mechanism on the basis of flexure hinge and piezoelectric actuator is designed in this paper, and its kinetic model is given, and furthermore the digital olosed-loop control system combined with nanosensor and computer control system is developed. The experiment shows that the positioning accuracy of the nanopositio...
